Suppose that 250 mL of 050 M K2CrO4 aq reacts with 150 mL of

Suppose that 25.0 mL of 0.50 M K2CrO4 (aq) reacts with 15.0 mL of AgNO3 (aq) completely. What mass of NaCl is needed to react with 35.0 mL of the same AgNO3 solution?

Solution

25*0.5*2=15*molarity of agno3.....molarity=1.6667

1.667*35*1= (m/58.5)*1000

58.345=(m/58.5)*1000

m= (58.345*58.5) /1000

=3.413 gms
