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)

Respuesta :

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

Answer:

0.8100 g/mL

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,

[tex]\rho = \frac{m}{v}[/tex]

[tex]\rho = \frac{292.2 - 130.2}{200.0}[/tex]

[tex]\rho = \frac{162.0}{200.0}[/tex]

[tex]\rho = 0.8100[/tex]

Thus, the density of oil = 0.8100 g/mL
