Question

How many molecules are in 4.5 moles of Ca(OH),?​

Answer 1

Answer:

We will use dimensional analysis to solve this.

We will need to know Avogadro's number, which is 6.02 × 10²³.

4.5 mol × $\frac{6.02 * 10^{23} molecules}{1 mol}$ = 2.71 × 10²⁴ molecules.

There are 2.71 × 10²⁴ molecules in 4.5 moles of Ca(OH).

Answer 2

61 molecules will be the answer most definitely :)
