  • #1 Scelta multipla
    A solution is prepared by dissolving 8.2 g of glucose (molar mass = 180 g/mol) in enough water to make 620.0 g of solution. What is the mass percent of glucose in the solution? Use the formula: $\text{Mass percent} = \frac{\text{mass of solute}}{\text{mass of solution}} \times 100$
  • #2 Scelta multipla
    If you have 5.0 g of NaCl dissolved in 95.0 g of water, what is the mass percent of NaCl in the solution? $\text{Mass percent} = \frac{\text{mass of solute}}{\text{mass of solution}} \times 100$
  • #3 Scelta multipla
    A biochemist needs to prepare 100 g of a 10\% (w/w) glucose solution. How many grams of glucose and water are required?
