The formula for mass you can find from the density equation. Multiply the volume by both sides of the equation.

density = mass/volume

volume*density = mass 

And there you are :)

There are a few ways to calculate mass. You can do Density * Volume. But you can also do Weight/Gravitational Constant (9.81 m/s2 on earth)
