If 2.45 g of sugar is dissolved in 200.0 g of water, what is the mass percent of sugar in the resulting solution?

• A. 1.22%
• B. 0.012%
• C. 2.45%
• D. 0.98%

Answer: (A)

Verified step by step guidance

1. Identify the given quantities: mass of sugar (solute) = 2.45 g, mass of water (solvent) = 200.0 g.
2. Calculate the total mass of the solution by adding the mass of the solute and the solvent: \(\text{mass of solution} = \text{mass of sugar} + \text{mass of water}\).
3. Use the formula for mass percent, which is the mass of the solute divided by the total mass of the solution, multiplied by 100: \(\text{mass percent} = \left( \frac{\text{mass of solute}}{\text{mass of solution}} \right) \times 100\).
4. Substitute the known values into the formula: \(\text{mass percent} = \left( \frac{2.45}{2.45 + 200.0} \right) \times 100\).
5. Perform the division and multiplication to find the mass percent of sugar in the solution.
