How do i find the mass of a metal paint bucket?

9.8 m/s^2 is the acceleration due to earths gravity. calculate the volume of the paint bucket. multiply it by 7.65 to get the mass.

D= M/V\n\nIts a formula used to calulated to density (thinkness) of an object by dividing the Mass of an object by its volume. In this case, you can use the water displacement method that displaces (water) from its orignal volume by adding an object (marble). Using a balancer, measure and record the weight of graduated cylinder(ml), before and after the addition of water. Subtract the weight of the cylinder with water from the cyliner's weight and you will get the mass. You have to pay attention to how much the water displacement after adding the marble. record the volumes before and after (if ness). This will solve for volume. Once this is accomplished, you would have no problem finding the density.

well, first start with the molecular weight of gold (197 by definition), then divide it by the number of atoms in a mole (6.2*10^23), which gives you a mass of 3.18*10^-22 g.

Zero out all scales. You start will the scale with the largest ballast (big heavy thing). Move it larger by notches until the scale tips the other way, then move it back one notch. Repeat this on each successively smaller scale. Then your weight is the sum of each scale.\nSo 150 + 10 + 5 + 3 would be 168.

mass initial = Mi\nmass final = Mf\n\nMass growth = Mf - Mi\nPercent growth = Mf/Mi * 100

All you need to do is know the density of water- not too difficult to find! THe psi necessary to support a column then must match the weight of that column. So, if a column is 1inch in area and Hinches high, if you know D the density of water per cubic inch in pounds, the height of the column in inches times this value is the psi needed.\n\nPressure psi=H*D\n\nThis also works for metric, just use cms and kgs as the base sizes.

Facts to remeber while solving the physics problem\n1. A force that causes an object with a mass of 1 kg to accelerate at 1 m/s is equivalent to 1 Newton.\nWe will also be using the principles based on Newton's Laws of motion.\nEarth attracts a mass of one kilogram with a force of about 10 newtons.\nIn Physics weight and mass are different. The mass of a body does not change, the weight will depending on the gravitational pull acting on it.\n   \nF = m x a       \nWhere    m = mass (kg) \n      F = force (N) \n      a = acceleration (m/s/s) \nTo calculate the downward pressure on the bottom of the bucket .\nWe first calculate the force on a 1 Kg bucket (given) due to 30 cm(change to metres 1 m = 100cms) of water\nF =  1 x 0.3 x 0.3 = 0.09N\nTherefore total downward force on the bottom of the bucket is the addition of the two.\nTotal downward force = 10N + 0.09 N = 10.09N\n\nTo calculate weight of full bucket.\nWe know bucket weighs 1 Kg\n12 litres of water = 12 kg\ntherefore total mass = 13 kg\n1 Kg = 10N\nTherefore 13 Kg = 130N\nWight of full bucket = 130 N

D = M/V\n\nDensity= Mass/Volume

density=mass/volume or something like that, so if u have the density and the volume (aproximations ofcourse) u can find the mass\n\ni think! lol

Let's make this very simple.\n\nTo measure the volume of a cylinder, you find the diameter of the interior portion of the cylinder.  Take that number and divide by two...that's your radius (r).  Now measure the height of the interior of your cylinder...that's your height (h).\n\nNow, take the radius (r) and the height (h) and plug them into the formula below:\n\nV = π*(r)*(r)*(h)\n\n(π equals roughly 3.1516)\n\nNow if your answer is in cubic inches, multiply V by .0036 for British gallons or .00433 for US gallons (yes, they are different).  If V is in cubic centimeters, multiply by .00022 (British) or .00026 (US).\n\nI don't know how to make it any clearer...good luck.

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

need to know the type of metal, then find the shear force & plug it into your equation.  don't forget to factor in each thread  (Basic solid mechanics)

OMG!\ni have the same question!\nmine is:\nA piece of an unknown metal has a mass of 20.0 g and at 100.0 C is placed in a styrofoam cup calorimeter containing 50.7 g of water at 22 C. If the final temp is 27.2 C, calculate the specific heat capacity of the metal. Assume that all the energy lost by the metal is gained by the water.\n\nok, haha fine, not the SAME question, but close enough. But, i'm uber confused. ><

Determining the mass is trivial: just weigh the block.  For the density, you will need to know the volume, which will require some measuring with a ruler.  Then divide the mass by the volume for your answer.

Simply d1/ d2 = weight of metal / loss of weight in water = 10/ 2 = 5.\n\nd1 = 5x10^3 Kg/ m^3\n  \n\nDetails\n\nThe reduction in downward force is 2N.\n\nThis is due to the upward force given by equal volume of water. \n\nIf V is the volume and its mass is V.  10^3 ( density of water is 10^3 kg/m^3).\n\nThe weight of this volume of water is V.  10^3 g This is equal to 2N. \n\nThe weight of the metal is V. d . g ( d is the density of the metal) = 10N.\n\nTherefore,  V.  d . g/ V.  10^3 g ==10/ 2 = 5\n\nd = 5 x10^3 kg/m^3.

ya you would just go density divided by the mass and then you get the volume  make sure you density is grams/ml and then your mass should be ml and then your volume would turn out to be grams. good luck
