Please help! It is due in an hour and I'm solving other problems in this assignment, but just can't get this one. If you use a volumetric pipet to transfer 10 mL of a 0.401 M stock solution into a 50 mL volumetric flask and then filled the flask to the calibration mark with deionized water, what would the concentration (in M) of the new solution be? Filling in a dilution diagram like the one below, may help you with this calculation.

Edit: 0.0802 M
Explanation: C1V1 = C2V2
We need to solve for C2 so set the formula to fit that.
C2 = C1V1/V2
C2 = (10 mL • 0.401 M)/ 50 mL = 0.0802M
