2.3   Calculate the molarity of each of the following solutions:

              (b) 30\; mL  of 0.5\; M  H_{2}SO_{4}  diluted to 500 \; mL.

Answers (1)

By conservation of moles we can write :  

                                              M1V= M2V2

Given that M1 = 0.5 M and V1 =  30 ml ;   V2 =  500 ml

                                              M_2 = \frac{M_1V_1}{V_2} = 0.03\ M
