Question

find the number of molecules Present in one mole of hydrogen gas.​

Answer 1

Answer:

Avogadro's number: The number of representative particles in a mole, 6.02 × 10 23 .

Answer 2

Answer:

1.2044 ×$10^{24$

Explanation:

This question requires an understanding of what avogadro's number actually represents.  Avogadro's number, 6.022 × 10^23  is the number of things in one mole.  The question indicates that there is 1 mole of H2.  Thus there are 6.022 *10^23 molecules of H2.  However the question is asking for the amount of atoms in 1 mole of H2.  Thus we must consider the makeup of an H2 molecule, where we see that it is a diatomic molecule.  Thus we must multiply 6.022 * 10^23 by 2 to calculate the number of individual atoms present in 1 mole of H2.  We find our answer to be 1.2044 * 10^24.
