The mole fraction of water in a solution of sugar in water is equal to 0.942. What is the mole fraction of the sugar?

The mol fraction of sugar is 0.058

Explanation:

Step 1: Data given

Molar mass of water = 18.02 g/mol

Molar mass of sugar = 180.16g/mol

Mol fraction of water = 0.942

Step 2: Calculate mol fraction of sugar in water

Mol fraction = number of moles of compound / total moles

The maximum number of mol fraction will be:

When number of moles = total moles

mol fraction = total moles / total moles = 1

This means the mol fraction of sugar = 1 - mol fraction of water

1.00 - 0.942 = 0.058

The mol fraction of sugar is 0.058
