Question

Moles = Mass/Molar Mass

Mass is 20g and the number of moles is 2 what is the molar mass?

Answer 1

• Mass=20g
• Moles=2

`\\ \sf\longmapsto Molar\:Mass=(Mass)/(Moles)`

`\\ \sf\longmapsto Molar\:Mass=(20)/(2)`

`\\ \sf\longmapsto Molar\:Mass=10g/mol`

Answer 2

mass = 20g

moles = 2

(The formulae used is given below)

Molar Mass -

`=>(mass)/(moles)`

`=> (20)/(2)`

(when you cancel by 2)

`=> (10)/(1) =10`

Molar Mass = 10g/mol
