Question

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?

Answer 1

Given,

`V = 20.0"mL"`

`m = 77.7572"g" - 45.8772"g" approx 31.880"g"`

Recall,

`rho = m/V`

Hence,

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