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

$\\ \sf\longmapsto Molar\:Mass=\dfrac{Mass}{Moles}$

$\\ \sf\longmapsto Molar\:Mass=\dfrac{20}{2}$

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

Answer 2

Answer:

mass = 20g

moles = 2

(The formulae used is given below)

Molar Mass -

$=>\frac{mass}{moles}$

$=> \frac{20}{2}$

(when you cancel by 2)

$=> \frac{10}{1} =10$

Molar Mass = 10g/mol
