Question

3.0 x 10 ^23 atoms of calcium to moles

Answer 1

`0.5\text{ mole}`

Step-by-step explanation:

Here, we want to get the number of moles

Mathematically:

`1\text{ mole has 6.02 }*\text{ 10}^(23)\text{ atoms}`

The number of moles in the question would be:

`\frac{3.0*10^(23)\text{ atoms}}{1}*\frac{1\text{ mole}}{6.02*10^(23)\text{ atoms}}\text{ = 0.5 mole}`
