How many moles are in 10 grams of CaCl2?

n = 0.0901 mole

Explanation:

n = m/Mm

n = number of mole

m = number of mass

Mm = number of molar mass

Given

CaCl2

m = 10grams

Mm of CaCl2

Ca = 40.078

Cl = 35.453

CaCl2 = 40.078 + 2 (35.453)

There are two atoms of Cl

= 40.078 + 70.906

= 110.984

m = 10g

n = m/Mm

Insert the values

n = 10/110.984

n = 0.0901 mole

The number of mole is 0.0901mole
