You have to know two out of three ... mass, volume, density ... then you can find the missing one.

If density is missing . . . Density = (mass)/(volume)

If mass is missing . . . Mass = (density) x (volume)

If volume is missing . . . Volume = (mass)/(density)

What is the mass of a sample divided by its volume?

Its density. Density is mass per unit volume.


If A sample of metal has a mass of 94.5 grams and a volume 7 cubic centimeters what is the density?

Based on the formula Desnity= Mass/Volume. The answer would be 13.5 g/cm3


What is density what is the formula how would you solve for volume how would you solve for mass?

density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density


What equation would you use to express the density of a mineral sample?

density = mass / volume


What volume of water would be displaced by 13.3543 g of a metal with a density of 7.51?

The basic formula for density is density = mass/volume. If you have mass and density, you can manipulate the formula so that volume = density x mass.


How would you determine the density of a powdered dry sample which soluble in water?

1. Apparent density: - weight a graduated cyllinder - put the sample in the graduated cyllinder up to a given volume (note this volume) - weight the graduated cyllinder with the sample - calculate the mass of the powder by difference - the density is the ratio mass of the sample/volume of the sample 2. True density of a powder: you need a helium pycnometer.


How do you find the mass knowing the density?

The formula for density is mass times volume. Therefore, density divided by volume would give you mass.


What formula would you use to calculate the density of an object?

mass/volume


The formula to calculate density?

Normally you would divide the mass by the volume.


How would you rearrange the density formula to calculate the mass or volume for an object?

density = mass/volumemass = density*volumevolume= mass/density


What volume would a 0.871 gram sample of air occupy if the density of air is 1.29g ml?

multiply the mass and the density


What formula would you use to find the mass of an object if you know density and volume?

Mass divided by volume equals density. or m/v = d.
