Answer 2

Given: $3.01×10^{23}$ atoms of Ca.

To find: We have to find the number of moles.

Solution:

To determine the number of moles we have to follow the below steps as follows-

Ca is an alkaline earth metal. It has the atomic number 20.

We know that $6.02×10^{23}$ atoms of Ca occupy one mole.

Thus $3.01×10^{23}$ atoms of Ca occupy-

$\frac{6.022 \times {10}^{23} }{3.01 \times {10}^{23} } = 2$

The result is 2.

So, $3.01×10^{23}$ atoms of Ca have 2 moles.
