What volume of ethanol must be diluted with
water to prepare 315 mL of 0.620 M solution?
The density of ethanol is given as 0.789 g/mL.
Answer in units of mL
1 answer
You want 315 mL of 0.620M = 0.315*0.620 = mols ethanol needed. mol = g/molar mass to give you grams, then use the density to calculate volume (mL) ethanol. Then to make this solution, you must add H2O to make a total volume of 315 mL.
