# An empty graduated cylinder weighs 45.8772 g. After 20.0 mL of a liquid is added, the cylinder and its contents weigh 77.7572 g. What is the density of the liquid in g/mL?

Given,

$V = 20.0 \text{mL}$

$m = 77.7572 \text{g" - 45.8772"g" approx 31.880"g}$

Recall,

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

Hence,

rho = m/V approx (1.59"g")/"mL"
