If we dissolve 55g of sugar (c12h22o11) in .800 liters of solution, what is the molarity?

We need to use the following formula:

Molarity = moles/ liters

1) we need to determine the moles by converting the grams to moles using the molar mass

molar mass C₁₂H₂₂O₁₁= (12 x 12.0) + (22 x 1.01) + (11 x 16.0)= 342 g/mol

55 g sugar (1 mol/ 342 g)= 0.161 moles

2) plug in the values into the molarity formula

molarity= 0.161 mol/ 0.800 Liters= 0.201 M
