Question

calculate number of moles of hydrogen in 0.448 litre of hydrogen gas at STP ​

Answer 1

Explanation:

1 mole of hydrogen gas at STP occupies 22.4 litres.

No. of litres of moles of hydrogen in 0.448 litre of hydrogen gas at STP =>0.448/22.4 =>

0.02 . Hope it helps you.

Answer 2

Dear Sandesh,

◆ Answer -

No of moles = 0.02 moles

● Explaination -

According to Avogadro's law, equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.

1 mol of gas occupies 22.4 L of volume at STP. Thus, no of moles of hydrogen is -

No of moles = volume / 22.4

No of moles = 0.448 / 22.4

No of moles = 0.02 moles

Thus, 0.448 L of hydrogen gas contains 0.02 moles of H2.

Thanks dear...
