Answer: mass = 19 grams
Explanation: Density is directly proportional to mass and indirectly proportional to the volume. So, the density formula is:
[tex]density=\frac{mass}{volume}[/tex]
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 [tex]\frac{5.2g}{cm^3}[/tex] and the volume is [tex]3.7cm^3[/tex] .
Let's plug in the values in the formula to calculate the mass:
mass = [tex]\frac{5.2g}{cm^3}*3.7cm^3[/tex]
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.
