Question

The density of benzene at 15 °c is 0.8787 g/ml. Calculate the mass of 0.1500 l of benzene at this temperature. Enter your answer in terms of grams

Answer 1

131.8 g.

Step-by-step explanation:

• There is a relation that relates the density of the substance (d) to the mass (m) and the volume of the substance (V):

d = m / V.

d = 0.8787 g/ml.

V = 0.15 L x 1000 = 150 ml.

• ∴ the mass of 0.15 L of benzene = d x V = (0.8787 g/ml) (150 ml) = 131.8 g.
