A student dispensed 20.00 mL of 2x10^-5 M blue #1 solution into a test tube. He then added 2.00 mL of NaCl solution and 2.00 mL of 2.50 % bleach solution.
a) calculate the molarity of the 2.50% bleach solution assume the density of the solution is 1.00g/mL
b) calculate the molarity of the bleach in the mixture(= blue#1 +Nacl+bleach)
