what density of refrigerant 123?
480669
Refrigerant 123 is more correctly known as 2,2-dichloro-1,1,1-trifluoroethane.  Density is 1.4638 g/cm3
763787
For the temperature of 277K (4 degrees Celsius) it is 1000kg/m^3, so it is 1kg/dm^3 (dm^3 is one liter), 1g/cm^3 (cm^3 is one milliliter). 4 degrees Celsius is the temperature of the highest density of water.

Does density affect  items when temperature, humidity, and  gravity are changed?

You use the formal \nH= mcdeltat\n\nmanipulate it to be...\n\nc (specific heat capactiy) = H /(mdelta t)\n\nChange temperature to Kelvin,....4degrees = 277Kelvin\n\nC=221/(55X277)\n\n\nC= 221/15235\n\nC=0.0145 (in JOULES)

The density of the fluid and the density of the object.

If you're in the US, 1 is true, otherwise not, eg in the UK.\nTransition metals are the most dense.\nFluorine, 1s2, 2s2, 2p5 is the most reactive halogen.\nFluoride ion is 1s2, 2s2, 2p6.

Why not take a page from Archimedes' Eureka! moment?\n\nMeasure the density, then ask a jeweler.

Properties of Fluids \nThe properties outlines below are general properties of fluids which are of interest in engineering. The symbol usually used to represent the property is specified together with some typical values in SI units for common fluids. Values under specific conditions (temperature, pressure etc.) can be readily found in many reference books. The dimensions of each unit is also give in the MLT system (see later in the section on dimensional analysis for more details about dimensions.) \n\nDensity \nThe density of a substance is the quantity of matter contained in a unit volume of the substance. It can be expressed in three different ways. \n\nMass Density \nMass Density, , is defined as the mass of substance per unit volume. \n\nUnits: Kilograms per cubic metre, (or ) \n\nDimensions:  \n\nTypical values: \n\nWater = 1000, Mercury = 13546 Air = 1.23, Paraffin Oil = 800. \n\n(at pressure =1.013and Temperature = 288.15 K.) \n\nSpecific Weight \nSpecific Weight , (sometimes , and sometimes known as specific gravity) is defined as the weight per unit volume. \n\nor \n\nThe force exerted by gravity, g, upon a unit volume of the substance. \n\n\nThe Relationship between g and  can be determined by Newton's 2nd Law, since \n\n\nweight per unit volume = mass per unit volume g\n\n\nUnits: Newton's per cubic metre, (or ) \n\nDimensions:. \n\nTypical values: \n\nWater =9814 , Mercury = 132943 , Air =12.07 , Paraffin Oil =7851  \n\n\nRelative Density \nRelative Density, , is defined as the ratio of mass density of a substance to some standard mass density. \n\nFor solids and liquids this standard mass density is the maximum mass density for water (which occurs at c) at atmospheric pressure. \n\n\n\nUnits: None, since a ratio is a pure number. \n\nDimensions: 1. \n\nTypical values: Water = 1, Mercury = 13.5, Paraffin Oil =0.8. \n\n\nViscosity \nViscosity, m, is the property of a fluid, due to cohesion and interaction between molecules, which offers resistance to sheer deformation. Different fluids deform at different rates under the same shear stress. Fluid with a high viscosity such as syrup, deforms more slowly than fluid with a low viscosity such as water. \n\nAll fluids are viscous, "Newtonian Fluids" obey the linear relationship \n\ngiven by Newton's law of viscosity. , which we saw earlier. \n\nwhere  is the shear stress, \n\nUnits ;  \n\nDimensions. \n\nis the velocity gradient or rate of shear strain, and has \n\nUnits: , \n\nDimensions  \n\n is the "coefficient of dynamic viscosity" - see below. \n\n\nCoefficient of Dynamic Viscosity \nThe Coefficient of Dynamic Viscosity, , is defined as the shear force, per unit area, (or shear stress ), required to drag one layer of fluid with unit velocity past another layer a unit distance away. \n\n \n\nUnits: Newton seconds per square metre, or Kilograms per meter per second,. \n\n(Although note that  is often expressed in Poise, P, where 10 P = 1 .) \n\nTypical values: \n\nWater =1.14  , Air =1.78  , Mercury =1.552 , \nParaffin Oil =1.9 . \n\n\nKinematic Viscosity \nKinematic Viscosity, , is defined as the ratio of dynamic viscosity to mass density. \n\n\n\nUnits: square metres per second,  \n\n(Although note that n is often expressed in Stokes, St, where St = 1 .) \n\nDimensions: . \n\nTypical values: \n\nWater =1.14  , Air =1.46  , Mercury =1.145  , \nParaffin Oil =2.375  .

Use:\n\npressure = density x height x g\nwhere g = 980 cm/s^2\n\nfor each liquid.  the answer (in dynes) will be the sum of the two pressures.

73.93 grams\nFirst you use the Ideal Gas Law: PV=nRT >P is pressure in atm., V is volume, n is moles, R is the constant: .0821, T is the temperature in Kelvins> (1atm.)(3.16L)=(n)(.0821)(305K) > .126195563 moles. Now you use a proportion. 9.33grams/.126195563moles = x grams/ 1 mole > 73.93 grams

You might be referring to brass, which has a density of 8.5 g/ml.\n\nBronze with 11% tin has a density of 8.1 g/ml.\n\n\nI would guess the brass, since it is more commonly used.

A general form of the equation I beleive you are looking for comes from a basic understanding of thermodynamics.  I am assuming that your ct=(Tfinal-Tinitial)...\n\nSo a general form of the equation would be:\nmCp(Tf-Ti)=Q \n\n"Cp is the specific heat"\n\nWATCH UNITS!!!!!  \n(I am ignoring the conversions in this statement)\n55g*Cp(67degrees UNITS)=343 cal \n\nSolving this equation will give you Cp ... just make sure that you watch units.
