Question

A flask containing 5.98mL of a liquid weighs 163.4 g with the liquid in the flask and 154.9 when empty. Calculate the density of the liquid in g/mL to the correct number of significant digits

Answer 1

1.42 g/mL

Step-by-step explanation:

The mass per unit volume is called as density. It is an intensive property and its value doesn't depend upon the amount of a substance.

It is given as,

Density = Mass / Volume

Data Given:

Mass of Liquid + Flask = 163.4 g

Volume of Liquid = 5.98 mL

Mass of empty Flask = 154.9 g

Mass of Liquid = 163.4 g - 154.9 g = 8.5 g

Formula Used:

Density = Mass / Volume

Density = 8.5 g / 5.98 mL

Density = 1.42 g/mL
