1)Calculate the final concentration of each of the following:

2.6 L of a 5.0 M HCl solution is added to water so that the final volume is 7.0 L . Cfinal = ? M

Water is added to 0.40 L of a 12 M NaOH solution to make 4.0 L of a diluted NaOH solution. Cfinal = ?M

A15.0 −mL sample of a 16 % (m/v) KOH solution is diluted with water so that the final volume is 120.0 mL . Cfinal = % (m/v)

A 75.0 −mL sample of a 18 % (m/v) H2SO4 solution is added to water to give a final volume of 410 mL . Cfinal = % (m/v) 3)

2)Calculate the final concentration of the solution when water is added to prepare each of the following solutions.

17.0 mL of a 15.0 %(m/v)

K2SO4 solution is diluted to 80.0 mL Answer should be in % (m/v) 80.0 mL of a 6.00 M NaOH solution is diluted to 235 mL Answer should be in M
