Air is $21 \%$ oxygen by volume. Oxygen has a density of $1.31 \mathrm{~g} / \mathrm{L}$. What is the volume, in liters, of a room that holds enough air to contain $55 \mathrm{~kg}$ of oxygen?

Solutions

VerifiedIn this problem, we solve for the **liters of a room** that holds enough air to contain 55 kg of oxygen. The following are the given values that will be used to solve for the unknown:

Percent oxygen by volume in air = 21%

Density of oxygen = 1.31 g/L

Oxygen capacity of the room = 55 kg

To solve for this, we must get the equivalent volume of oxygen that can fit the room and get the total volume of air.

The goal of this exercise is to determine the volume of a room in liters that contains enough air with 55 kg of oxygen; given that oxygen has a density of 1.31 g/L, and air is basically 21% oxygen by volume.
