Question

How many moles are there in 1.3 x 10^24 atoms of calcium

Answer 1

n=2.2 mole

explanation

n=N/A

N=1.3×10^24

A=6.022×10^23

`\frac{1.3 * {10}^(24) }{6.022 * {10}^(23) } = 2.2`

n=2.2 mole

Answer 2

Number of moles in 6.23 x 10^23 = 1 .

So , In 1.3 x 10^24 = 1.3 * 10^24 / 6.23 * 10^23 => 2.2 Moles .
