A 500 gal capacity tank initially contains a salt solution consisting of 200 gal of water and
3 lbs of salt/gal. A solution of 2 Ib/gal flows in at the rate of 3 gal/min and the resulting
mixture flows out at the rate of 2 gal/min. What is the concentration in the tank when it
starts to overflow?
O 2.352 Ib/gal
O 1.873 lb/gal
O 1032 lb
O 2.064 lb/gal
A solution is prepared by dissolving 50 grams of salt in 250 centimeter cube of water. Find the density of the solution [Take the density of water =1.0 gram per centimeter cube]
Red gold is a gold-copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.50 g and has a volume
of 0.583 cm. Gold has a density of 19.3 g/cm³ and copper has a density of 8.96 g/cm³. Calculate the percentage by mass of
each metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains.

Pure gold is defined as having 24 carats. When mixed in an alloy, the carats of gold are given as a percentage of this value.
For example, a piece of jewelry made with 50% gold has 12 carats. State the purity of this piece of red gold jewelry
in carats.
