Question

Calculate the number of atoms in 5 mole of Helium. ​

Answer 1

Answer:

30.11 x 10^23

Explanation:

no. of atoms = moles x avagardo number

=5 x 6.022 x10^23

=30.11 x 10^23

Answer 2

Explanation:

$no. \: of \: moles = \frac{no. \: of \: atoms}{avogadro \: constant}$

$5 = \frac{n}{6.02 \times {10}^{23} }$

$no. \: of \: particles = 30.1 \times {10}^{23}$

Therefore, it is your answer.
