1. We are given :
• n = 4.12 mol
• at STP , we know that :
According to avogadro's law at STP 1 mole of gas occupy volume 22.414 L
2. Calculations :
If 1 mole : 22.424L
then,4.12mole : x L .......(do a cross multiply)
Therefore ; x L = 4.12Mole * 22.424L/ 1 mole
=92.38 Litres
≈92.4 L
• This means that 4.12 mol sample of hydrogen gas will occupy ,92.4 Litres
