How many grams of the compound in the figure are required to make 1 litre of a 0.5 M solution? (Note: The atomic masses, in daltons, are approximately 12 for carbon, 1 for hydrogen and 16 for oxygen.)

Question

Quizplus · Accepted Answer

0.5 M solution means 0.5 moles of solute per liter of solution. The molar mass of the compound is 12 + (1 x 4) + (16 x 2) = 60 g/mol. Therefore, 0.5 moles of the compound weighs 0.5 x 60 = 30 grams.
