How to calculate density - Office Equipment & Supplies

The density and the volume?

Density is 7.85g/cm^3.

Volume is length x width x height.

Good luck.

About 1.157 g/ml

Divide the mass (100 g) by the volume (50 cm^3).
Density =100 g /50 cm^3 =2 g/cm^3

Do not blame your calculator. Get a plausible average mass density for the concrete (dry or wet) and multiply the density by the volume.

Yes. The density is simply the mass divided by the volume. If you know any two of the above then you can calculate the third.

Density =mass/volume =(5 g)/(2 cm^3)=2.5 g/cm^3

A cubic foot is a unit of volume. A pound can be a unit od mass (weight) or a currency. Either way a volume cannot be converted into a mass nor a currency.
If you are doing homework read carefully the question to figure out what substance they are talking about.
Once you know the substance look up its density or specific gravity and do the calculation
mass (in pouunds) =density (in pounds per cubic foot) * volume (in cubic feet)

As you see, if you know the density (specific gravity) in pounds per cubic foot, you can calculate the mass of any volume of that substance (in cubic feet).

And please, never try to convert a volume into a mass.

You already know the density, so the temperature and the pressure doesn't matter So just multiply 1.2 x 5 = 6 gallons

The pressure and temperature are irrelevant since u know the density. So all you need to do is. 1.2 x 5=6 gallons Gallons is a unit of volume, if u need the answer in a different unit just repost

The density is the mass divided by the volume. Divide 405 by 0.15 to get the density in kg/cubic-meter.
