How many atoms are there in one mole of hydrogen gas? [Avogadro’s constant = 6.02 x 1023mol-1]
- 1.2 x 10 23
- 6.0 x 10 23
-
1.2 x10 24
- 6.0 x 10 24
The correct answer is: C
Explanation
One mole of hydrogen gas has 6.02 x 1023 molecules, and one molecule of hydrogen gas contains 2 atoms of hydrogen
therefore, one mole of hydrogen gas will contain 2 x 6.02 x10^23 atoms
= 1.2 x 10^24 hydrogen atoms
