Question

Calculate the number of moles in 32.0 g of CaCl2

Answer 1

n = 0.288 moles

Step-by-step explanation:

Given mass = 32 g

The molar mass of CaCl₂ is:

M = 40.078 + 2(35.453)

= 110.98 g/mol

We need to find the number of moles in 32 g of CaCl₂. Let there are n no of moles.

`n=\frac{\text{Given mass}}{\text{Molar mass}}\\\\=(32)/(110.98)\\\\=0.288`

So, there are 0.288 moles in 32 g of CaCl₂
