Question

How many atoms of hydrogen are there in 2.5 moles of H?

Answer 1

Explanation:

with 2.50 mol, 2.50 mol H * 6.02 * 10^23 atoms H / 1 mol H = 1.51 * 10^24 atoms H.

Answer 2

Answer:

1.506 × 10^24 atoms.

Explanation:

No. of atoms present in one mole of hydrogen

$= 6.023 \times {10}^{23}$

Therefore number of atoms in 2.5 moles

$= 2.5 \times 6.023 \times {10}^{23}$

$= 1.506 \times {10}^{24}$
