Answer

Explanation:

Step1: Find mass of solution

Mass of solution = mass of solute + mass of solvent = (2.0,\text{g} + 48,\text{g} = 50.0,\text{g})

Step2: Calculate mass percent

Using formula (\text{Mass percent} = \left(\frac{\text{mass of solute}}{\text{mass of solution}}\right) \times 100) Substitute values: (\frac{2.0,\text{g}}{50.0,\text{g}} \times 100 = 4.0%)

Answer:

  1. 4.0%
