Question

To what volume should you dilute 30mL of a 11M H2SO4 solution to obtain a 0.17M H2SO4 solution?

Answer 1

Use the formula: \(\sf \color{red}{M_1V_1=M_2V_2}\)

that is your molar concentration initial multiplied by initial volume, equals final molar concentration (what you want).
Solve for V\(_2\).
Use algebra here.
