Question

How many atoms are in 2.50 mol of hydrogen?

Answer 1

Answer:

No. of atoms in 2.50 of hydrogen = $1.50\times 10^{24}\ atoms$

Explanation:

Moles of Hydrogen = 2.50 mol

Number of atom = Moles × Avogardro's no.

Avogadro's no. = $6.02 \times 10^{23}atoms$

Number of atom = Moles × Avogardro's no.

$=2.50 \times 6.02 \times 10^{23}\\=1.50\times 10^{24}\ atoms$

So, no. of atoms in 2.50 of hydrogen = $1.50\times 10^{24}\ atoms$

Answer 2

To do this, you must multiply the number of moles by the Avogadro's number, 6.0221409e+23

So, with 2.50 mol,

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

To make that statement clearer, in 2.50 mol of Hydrogen, there are 1.51x10^24 atomsH
