PROBLEM 61P

A cylinder contains 28.5 L of oxygen gas at a pressure of 1.8 atm and a temperature of 298 K. How many moles of gas are in the cylinder?

Solution 61P

Given:

Volume = 28.5 liters

Temperature = 298 K

Pressure = 1.8 atm

Want to know: Number of moles of gas

Explanation:

According to the ideal gas law, it is known that

P⋅V=n⋅R⋅T

Since we are looking for number of moles of gases, we will rearrange the equation

n=

R is...
