Question

what is the volume of 2gm of H 2 gas at STP ? number of molecules present in one molecule of a gas
pls help tomorrow is my exam !!
no spams!!​

Answer 1

Answer:

11.2L

Explanation:

Volume of H_(2) gas occupied by its one equivalent at S.T.P. is. =11.2L at S.T.P.

Answer 2

Answer:

According to this, one mole of hydrogen gas at STP will occupy 22.4 L of volume. Therefore, 2 moles of hydrogen gas will occupy a volume twice of 22.4 L i.e. 44.8 L.

Explanation:

Each contains 1 mole or 6.02 × 10 23 particles. However, the mass of each gas is different and corresponds to the molar mass of that gas: 4.00 g/mol for He, 28.0 g/mol for N 2 , and 16.0 g/mol for CH 4 .
