Question

How many moles are in a 60gram sample of NaCI

Answer 1

`1.03\text{ moles}`

Explantion

Here, we want to get the number of moles in 60 g sample of NaCl

Mathematically, to get this, we have to divide the mass given by the molar mass of NaCl

Thenmolar mass of NaCl is 58.44 g/mol

Thus, we have the number of moles as:

`(60)/(58.44)\text{ = 1.03 mole}`
