Reference no: EM13537100

A solution of ethanol (d=0.795 g/mL) and water is prepared by placing 30.0 mL of ethanol in a 250.0 mL volumetric flask and diluting with water to the flask etched mark.

What is the molarity of the ethanol?

next, 25.0 mL of the solution above is diluted to a final volume of 500.0 mL. What is the new molarity of the diluted solution?
