Question

A urine sample has a mass of 147 g and a density of 1.020 g/mL. What is the volume of this sample?

Answer 1

So we know that the equation for density is:

$D=\frac{m}{V}$

where D is the density, m is the mass in grams, and V is the volume in mL.

So since we know two of the variables, mass and density, we can solve for the volume:

$\frac{1.020g}{mL}=\frac{147g}{V}$

$V=\frac{147g}{\frac{1.020g}{mL}}$

$V=144.12mL$

Therefore, the volume of this urine sample is 144.12mL.
