Question

A 200.0mL beaker filled with oil has a mass of 292.2 g. The

mass of just the beaker is 130.2 g. What is the density of oil?
(4 sig figs)

Answer 1

p=m/v
p=(292.2-130.2)/200
p=0.8100g/ml

Answer 2

0.8100 g/mL

Step-by-step explanation:

Given,

Volume of the beaker, v = 200.0 mL

Weight of the beaker with oil in it = 292.2 g

Weight of the empty beaker = 130.2 g

Need to find = Density (ρ)

We know that,

`\rho = (m)/(v)`

`\rho = (292.2 - 130.2)/(200.0)`

`\rho = (162.0)/(200.0)`

`\rho = 0.8100`

Thus, the density of oil = 0.8100 g/mL
