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)
density = mass/volumemass = density*volumevolume= mass/density
The one which has a density of 2.5 g/ml (making its volume 8 ml).
To find density, you must use the formula of D=M/V or density = mass divided by volume. You have given us 9g as a volume, but that should be either liters or some other measurement of volume. I'll assume liters. 45/9 = 5. So, The density of a solid that has a mass of 45 grams and a volume of 9.0 liters would be 5 grams/liter.
This would depend on its volume and mass. Density = mass / volume. If the cotton is compressed it will occupy less volume, so the density becomes greater.
8.57 g D=mass/volume Wanting to fight weight of the vial so you would use Mass=density*volume 8.6mL is volume .997g/mL is density
Its density. Density is mass per unit volume.
Based on the formula Desnity= Mass/Volume. The answer would be 13.5 g/cm3
density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density
density = mass / volume
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.
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.
The formula for density is mass times volume. Therefore, density divided by volume would give you mass.
mass/volume
Normally you would divide the mass by the volume.
density = mass/volumemass = density*volumevolume= mass/density
multiply the mass and the density
Mass divided by volume equals density. or m/v = d.
