How many grams of 02 are present in 7.49 L of oxygen gas?

10.70grams

Explanation:

Density of a substance = mass/volume

At STP of a gas (standard temperature and pressure), the density of oxygen gas is 1.429 g/L

Hence, according to this question, in 7.49 L of oxygen gas, there would be:

Using D = m/V

1.429 = m/7.49

m = 1.429g/L × 7.49L

m = 10.70g

it would be d. henry moseley
