Question

What is the weight percent of vitamin C in a solution made by dissolving 1.30 g of vitamin C, C6H8O6, in 55.0 g of water?

Answer 1

`\text{Weight\% = }\frac{Mass\text{ solute}}{\text{Mass solute +Mass solvent}}\text{ x 100}`

Solute = vitamin C

Solvent = water

`\text{Weight \% = }\frac{1.3\text{ g}}{1.3\text{ g + 55.0 g}}\text{ x 100 = 2.3 \% of vitamin C}`
