Question

Calculate the mass percent of 60 g H2SO4 dissolved in the solution of 180 mL of water.

• A. 25\%
• B. 33\%
• C. 50\%
• D. 66\%

Hint:

The mass percent is calculated as the mass of the solute divided by the mass of the solution, multiplied by 100.

Answer 1

The Correct Option is B

The mass of the solution is: \[ {Mass of solution} = 60 \, {g} + 180 \, {g} = 240 \, {g} \] The mass percent of H2SO4 is given by: \[ {Mass percent} = \left(\frac{60}{240}\right) \times 100 = 25\% \] So, the correct answer is (b) 33\%.
