A solution is made by combining 4.00 g of sugar and 100 mL of water (density = 1.00 g\mL). What is the concentration in % w\w?
A)26.0
B)4.00
C)0.0400
D)3.85

Question

Quizplus · Accepted Answer

The concentration in % w/w is calculated by taking the mass of the solute (sugar) and dividing it by the total mass of the solution (solute + solvent), then multiplying by 100. The mass of water is 100 mL * 1.00 g/mL = 100 g. Total mass = 4.00 g (sugar) + 100 g (water) = 104 g. Concentration = (4.00 g / 104 g) * 100 = 3.85%.
