Question

find the no. of hydrogen atom present in 11.2 litre of hydrogen gas​

Answer 1

Answer:

Therefore, 0.5 mol of H2 has 0.5 x 6.022 x 1023 = 3.011 x 1023 molecules. Hence, the number of moles, molecules and atoms present in 11.2 liters of H2 at STP are 0.5 , 3.011 x 1023 and 6.022 x 1023 respectively.

Answer 2

Answer:

6.022x10^23 hydrogen atoms

Explanation:

hydrogen gas consist of H2 molecules ,if we talk about 11.2 litre of hydrogen gas then it will contain 0.5 moles of H2 molecules because 22.4 litre of a substance constitute to 1 mole or 6.022x10^23 ,half of that is 3.011×10^22 H2 molecules . therefore it will contain 6.022×10^23 hydrogen atoms
