# A single patient hyperbaric chamber has a volume of 640 L at a temperature of 24°C. How many grams of oxygen are needed to give a pressure of 1.6 atm?

Approx. $1300 \cdot g \ldots \ldots$

#### Explanation:

From the Ideal Gas Equation.........

$n = \frac{P V}{R T} = \frac{1.6 \cdot \cancel{a t m} \times 640 \cdot \cancel{L}}{0.0821 \cdot \frac{\cancel{\cancel{L} \cdot a t m}}{\cancel{K} \cdot m o l} \times 297 \cdot \cancel{K}} = 42.0 \cdot m o l$

Which represents a mass of 42.0*molxx32.0*g*mol^-1=??g.

Would it be a good idea to light up a smoke in such a chamber?
