Helium has a density of 1.79 x 10-4 g/mL at standard temperature and pressure. A balloon has a volume of 6.3 liters. Calculate the mass of helium that it would take to fill the balloon.

35,000 g
1.1 x 10-3 g
2.8 x 10-5 g
1.1 g

To find the mass you divide multiply volume and density..

Density = 1.79 x 10^-4     Volume = 6.3

(1.79 x 10^-4 )(6.3) =  1.1 x 10^-3 g

The mass of helium that it would take to fill the balloon is 1.1 grams.

What is the relation between mass and density?

Relation between the mass of any substance and their density will be represented as:

Density = Mass / Volume

Given that,

Density of helium gas = 1.79 × 10⁻⁴ g/mL

Volume of balloon in which gas is present = 6.3L = 6300 mL

On putting all these values, we get

Mass = (1.79 × 10⁻⁴ g/mL)(6300mL) = 1.12 grams

Hence required mass of helium is 1.1 g.
