Question:

What is the concentration of sugar (C12H22O11) in mol/L if 20g are dissolved in enough water to make a final volume up to 2L?

Solution:

Molarity = (Mass / Molar mass) × (1 / Volume)
The concentration of sugar (C12H22O11) is (20g / 342 g/mol) × (1 / 2L) = 0.029 mol/L.
molar mass of C12H22O11 = 342 g/mol
