Question

What is the molar mass of a substance that has a mass of 40 grams and a molar amount of 0.8 moles

Answer 1

The molar mass is 0.02 g/mol

Step-by-step explanation:

The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol).

`M=(n)/(m)`

We are given

`m=40` g

`n=0.8` mol

Substituting our values into the equation gives us

`M=(0.8)/(40)`

`M=0.02` g/mol
