A chemistry teacher adds 50 point 0 milliliters of 1 point 5 0 cap m cap h sub 2 SO sub 4 solution to 200 milliliters of water. What is the concentration of the final solution? Use cap m sub i cap v sub i is equal to cap m sub f cap v sub f
Answer
A
6 point 0 0 cap m
B
7 point 5 0 cap m
C
0 point 3 0 0 cap m
D
0 point 3 7 5 cap m
Explanation
Use the dilution equation MᵢVᵢ = M𝒇V𝒇. The final volume is 50.0 mL + 200 mL = 250 mL, so M𝒇 = (1.50 M × 50.0 mL) ÷ 250 mL = 0.300 M. The correct choice is 0.300 M.
