6.0 mL of a 6.0 M stock solution of potassium dichromate is diluted by adding 194.0 mL of water. Calculate the molarity of the resulting solution of K2Cr2O7.
Homework Answers
The formula is M1 V1 = M2 V2
M1 = 6 M, V1 = 6 mL, M2 = ?, V2 = 194
6 X 6 = M2 X 194
M2 = 26/194
= 0.134 M.
Molarity is 0.134 M
