Question

The density of benzene at 15 ∘c is 0.8787 g/ml. calculate the mass of 0.1000 l of benzene at this temperature.

Answer 1

V=0,1 l=100 ml
m=p*V=0,8787*100=87,87g

Answer 2

Answer: The mass of benzene is 87.87 grams

Explanation:

To calculate mass of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

Density of benzene = $0.8787g/ml$

mass of benzene = ?

Volume of benzene = 0.1000L = 100ml    $1L=1000mL$

Putting values in above equation, we get:

$0.8787g/ml=\frac{\text{Mass of benzene}}{100ml}$

Mass of benzene = 87.87g

Hence, the mass of benzene is 87.87 grams
