If the density of an object is 5.2 g/cm 3 , and its volume is 3.7 cm 3 , what is its mass?

mass = 19 grams

Explanation: Density is directly proportional to mass and indirectly proportional to the volume. So, the density formula is:

density and volume are given and the question asks to calculate the mass. So, the formula could be rearranged as:

mass = density x volume

Given density is and the volume is .

Let's plug in the values in the formula to calculate the mass:

mass =

mass = 19.24 grams

Both the density and volume have two sig figs, so if the answer is round off to correct number of sig figs then the mass will be 19 grams.

it is a good conductor
