Question

4.48L of CH4 at standard temperature pressure
​

Answer 1

Answer:

1 mole of gas occupies 22.4 litre volume at standard temperature and pressure conditions, which are 1 atm and 273K respectively. Hence, we can conclude that 22.4 litre is equal to 1 mole and it contains 6.022*10^23 molecules. So, 4.48 litre will contain 1.29*10^23 molecules
