Question

Problem No 5: How many moles does 11.2 L of hydrogen gas contain at STP? How many particles
(hydrogen molecules) does it contain?​

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.
