Question

The liquid pentafluorobenzene has a density of 1.51 g/mL at 20 °C. If a sample of this liquid at 20 °C has a volume of 2.08 L, how many grams of liquid are there in the sample?

Answer 1

There are 3.14 g of pentafluorobenzene is present in the sample.

What is Mass?

It is the measurement of how much amount of substance is present in the given volume.

$m = \rho \times V$

Where,

$m$ - mass

$\rho$ - dencity = 1.51 g/mL

$V$ - volume =  2.08 L = 2080 mL

Put the values in the formula,

$m ={ \rm 1.51 \ g/mL \times 2.08 \ L}\\\\m = 3.14 \rm \ g$

Therefore, there are 3.14 g of pentafluorobenzene is present in the sample.
