What is the volume of 3 moles of CO2 gas?
67.2 L
67.2 L
One mole of any gaseous molecule occupies 22.4 L and hence for 3 moles we just need to get the product of 22.4 and 3 = 67.2 L
One mole of an ideal gas will occupy a volume of 22.4 liters at STP (Standard Temperature and Pressure, 0°C and one atmosphere pressure)
