Explanation:
Standard volume=22.4 L
It means that 1 mole of any atom, molecule or ion occupies 22.4 L of volume at STP (Standard Temperature and Pressure)
1 mole of CO2 = 22.4 L
Given volume = 224 mL = .224 L ( 1 L = 1000 mL)
No. of moles in .224 L = Given volume/Standard volume
= .224/22.4 = 0.01 mole
