Question

How many moles are present in 100. g of aspirin (C3H804, molar mass 180.2 g/mol)?

Answer 1

0.555 moles

Step-by-step explanation:

Given,

Mass of aspirin = 100 g

Molar mass of aspirin = 180.2 g/mol

To find, moles of aspirin in 100 g of mass = ?

The formula for the calculation of moles is shown below:

`moles = (Mass\ taken)/(Molar\ mass)`

Thus,

`Moles= (100\ g)/(180.2\ g/mol)`

Moles of aspirin in 100 g = 0.555 moles
