Question

A chemistry teacher adds 50.0 mL of 1.50 M H2SO4 solution to 200 mL of water. What is the concentration of the final solution?
Use M subscript i V subscript i equals M subscript f V subscript f..
0.300 M
0.375 M
6.00 M
7.50 M

Answer 1

Use MiVi = MfVf.

Mf = (Mi Vi) / Vf = (1.50 M × 50.0 mL) / 250.0 mL = 75.0 / 250.0 = 0.300 M.

Answer: 0.300 M.
