1. How many grams of water must be added to 10.0 g of Ca(NO3)2 in order to prepare a
12.0%(m/m) solution?
2. Calculate the volume percent of solute in each of the following solutions. a. 20.0 mL of methyl
alcohol in enough water to give 475 mL of solution b. 4.00 ml of bromine in enough carbon
tetrachloride to give 87.0 mL of solution
3. For each of the following solutions, how many milliliters of water should be added to yield a
solution that has a concentration of 0.100 M?
a. 50.0 ml of 3.00M Nacl
b. 2.00 mL of 1.00 M NacI
c. 1.45 L of 6.00 M NacI
d. 75.0 mL of 0.110 M Nacl
4. Lead is a toxic substance. The "normal" lead content in human blood is about 0.40 part
per million (that is, 0.40 g of lead per million grams of blood). A value of 0.80 part per
million (ppm) is considered to be dangerous. How many grams of lead are contained in
6.0x10' g of blood (the amount in an average adult) if the lead content is 0.62 ppm?
5. Calculate the molarity of each of the following solutions:
(a) 29.0 g of ethanol (C,H,OH) in 545 ml of solution,
(b) 15.4 g of sucrose (C„H„01) in 74.0 mL of solution,
(c) 9.00 g of sodium chloride (NacI) in 86.4 mL of solution.
