1. A solution is made by dissolving 3.5 g of LiF in 3.75 liters of water at 80 C. Given that the
density of water at this temperature is 0.9718 g/ml, find the following:
a) Molarity
b) Mass percent
c) %m/v
d) Dilution Formula. If you take 2.0 liters of solution from (a) and add 1.5 liters of water
what
is the molarity of the resulting solution?
2. A solution is made by mixing 12 g ethanol (CH3CH2OH) in 88 g of water? (density of ethanol
0.789 g/ml, find the following: (Apts/1 pt each)
a) Molarity
b) % m/v
c) % vol/vol

d) Dilution Formula. If you take 2.0 liters of solution from (c) and add 1.5 liters of water what is
the % vol/vol of the resulting solution?
