1.) If 15.0 mL of 3.60 M HCl (aq) are added to 10.0 mL of water, what is the concentration of the resulting solution?
2.) How many mL of water must be added to 25.0 mL of a 0.500 M NaCl solution to result in a solution that is 0.200 M NaCl?
3.) The net ionic equation for the reaction of aqueous solutions of sodium chloride and silver nitrate is...?
4.) How many mL of a 0.500 M sodium chloride solution contains 0.100 moles of NaCl?
5.) The net ionic equation for the reaction of aqueous solutions of sodium sulfate and aluminum chloride is...?
Ans 1 :
Initial volume V1 = 15.0 mL
final volume V2 = 15.0 mL + 10.0 mL = 25.0 mL
initial concentration M1 = 3.60 M
using relation M1V1 = M2V2
3.60 M x 15.0 mL = M2 x 25.0 mL
M2 = 2.16 M
3.) The net ionic equation for the reaction of aqueous solutions of sodium chloride and silver nitrate is...? 4.) How many mL of a 0.500 M sodium chloride solution contains 0.100 moles of NaCl?
