# You have 1.45 Moles of Hydrogen. How many atoms are present?

Feb 21, 2018

$1.74638 \cdot {10}^{24}$ hydrogen atoms

#### Explanation:

In 1 mole of any element we know that there are $6.022 \cdot {10}^{23}$ particles.

$\therefore$ in $1.45$ moles there are:

$1.45 \cdot 6.022 \cdot {10}^{23} = 8.7319 \cdot {10}^{23}$ particles.

Hydrogen is diatomic going around as ${H}_{2}$

$\therefore$ $2 \cdot 8.7319 \cdot {10}^{23} = 1.74638 \cdot {10}^{24}$

$\approx 8.73 \cdot {10}^{23}$ atoms of hydrogen

#### Explanation:

Assuming that you are talking about single, unpaired $\left(H\right)$ atoms (which is unlikely), then we have the following:

In one mole of hydrogen atoms, there exists approximately $6.02 \cdot {10}^{23}$ hydrogen atoms.

So, in $1.45$ moles of hydrogen atoms, there will be

$1.45 \cdot 6.02 \cdot {10}^{23} \approx 8.73 \cdot {10}^{23}$ hydrogen atoms.
