Small children are occasionally injured when they try to inhale helium from a compressed helium tank. If a small child tries to transfer the contents of a 5.0 L tank of helium at a pressure of 125 atm and a temperature of 20⁰C into its lungs, how many moles of gas would the child inhale?

Answer:

26.0 moles

Explanation:

Given the formula;

PV =nRT

P= pressure of the gas

V = volume of the gas

n = number of moles of the gas

R = gas constant

T = temperature

n = PV/RT

n = 125 * 5/0.082 * (20 + 273)

n = 625/24.026

n = 26.0 moles
