I need help with a chemistry question its about density.?

to calculate the density you don't need to worry about the temprature and pressure if you already know the volume, as you do.\n\ndensity = mass per unit volume   \n\nit's standard units are g/cm^3\nyou volume is in mL, but that is fine since 1mL=1cm\n\ndensity = 1.6/15000\n=1.07x10^-4 g/cm^3

Density = mass / volume\nTo find the volume of an irregular object submerge it in water the amount the water rises is the volume of the object.

Density = Mass / Volume\n\nDensity of a substance is a measure of how much mass is present in a given unit of volume.

Density = mass / volume\nSo 514 g/500mL = ??? g/mL\nAnd that's all of your homework I'll do for you. ;)

In addition to the fact that at 4 degrees celcius, water has an absolute density of EXACTLY 1 g/cc, at 0 degrees, it is in equilibrium with its solid phase (ice) which has a density of LESS than 1 g/cc due to its open cage like crystal structure. So, its exact density at 0 degrees is impossible to standardise.

density,volume,weight,number of electron and proton.

i think it has something to do with the density...couldnt tell you exactly tho

density = mass/volume.\n it changes wt respect to temp.\n as temp increases,volume increases and so density decreases. however there may b some exceptions.\n  as an example, if v heat water to high temp but less than it's boiling point, it's volume increases.\n  so, v can say that the density is less than the previous condition.

Density is simply mass per unit volume.  The density of a substance is directly related to the atomic weight of the element composing it, ie., elements with higher atomic weight can be thought of as being “heavier”.   Another way of stating this is that equal volumes of two different substances have different densities because each different substance has a different mass (ie, atomic weight) and crystal structure.  There are many types of units which can be used to measure the mass of a substance (pounds, grams, etc.), just as there are many types of units which can be used to measure volume (cubic feet, cubic centimeters, etc.).  The standard units of measure for density are grams/cubic centimeter.  \n\nDifferent minerals or rocks can vary greatly in density, depending on their chemical make up.  Density is such a characteristic property of a substance that it may be used to identify the substance.  Geologists have found it useful to develop a system of comparing densities of different minerals or rocks by calculating a numerical value without units known as “specific gravity”.  The specific gravity is the weight of a substance compared to an equal volume of water.  Water is chosen as the substance for comparison because by definition it has a density of 1 gram per cubic centimeter (at 4o C), and also because it is such a common substance.  For example, compare the density of a rock like granite to water:  a cubic foot of water weighs 62.5 pounds and a cubic foot of granite weighs 168 pounds.  The specific gravity of granite is:   168 / 62.5  =  2.7.   Granite is 2.7 times heavier than water.

Can't give you a definite answer but as the primary ingredient will be water it will have a density very similar to that of water which is 1.000.

I'll agree that you need help.  Density is mass/vol.  You've given the density, you need another value to calculate the remaining value.

Water has a density maxima at 4C

Density is a function of two properties of matter- mass and volume.  So you're looking for a material that packs a lot of mass into a small space.  Probably the first hurdle the material has to clear is that it has to pe denser than itself in liquid form.  This is true of most materials that can legitimately have both a solid and liquid form, as the particles "pack in" closer together when they solidify and "spread out" as they liquify.  However, there are exceptions, like water, where the solid form is less dense than the liquid form (which is why ice floats).\n\nGenerally, as you move further up the periodic table into higher atomic numbers, elements get more dense (though exceptions certainly exist).  If you go very far up into the periodic table into say the Actinides (Uranium for example) you get into solids (largely unstable and radioactive, but solids nonetheless) that are extremely dense.  In theory however, at a high enough temperature you could possibly go further up the periodic table, heat the material to its melting point, and create a liquid that could potentially be more dense.

What element has the highest density?\n\n    Studies show that osmium and iridium share the highest densities. The reason why there are two is because there are slight discrepancies between the different measurement systems. Speaking of densities, a pinhead's volume of a piece of a dwarf star would weight more than the earth.

Density is mass divided by volume. 25 divided by 5 = 5 g/mL.\n\nDensity = 5 g/mL.

Water has its highest density at 4 deg. C.\n\nYou might try a Yahoo! search next time.  That's how I found the info.\n\nTake care,\nDavid Roth\nwww.tutor-homework.com
