Mass of CuSO4● XH2O (g) = 1.6 grams BEFORE HEATING
Leokris [45]

0.06105 moles is the number of moles of water lost.

<h3>What is molar mass?</h3>

Molar mass is defined as the mass in grams of one mole of a substance.

Given data:

Mass of water = 1.1g

Molar mass water = 18.016 g/mol

Moles of water =?

These quantities are related by the following equation;

Moles = \frac{Mass}{Molar \;mass}

Substituting the values of the quantities and solving for moles, we have;

Moles =  \frac{1.1 }{18.016} = 0.06105 moles.

Hence, the 0.06105 moles is the number of moles of water lost.
