Question

How many moles are in 59.75 grams of water?

Answer 1

n = 3.3167 moles

Explanation:

The number of mole in water

H2O

n = m/Mm

n = number of mole

m = number of mass

Mm = number of molar mass

Given :

Mass = 59.75g

Mm of H2O

H - 1.00784

O - 15.999

Mm

H = 2 * 1.00784 = 2.01568

O = 15.999

Mm of H2O = 15.999 + 2.01568

= 18.01468

insert the values into the formula

n = m/Mm

n = 59.75/18.01468

= 3.3167moles
