The total volume of ice in the Antarctic is about 3.01 × 10 7 km 3 . If all the ice in the Antarctic were to melt completely, estimate the rise, h , in sea level that would result from the additional liquid water entering the oceans. The densities of ice and fresh water are 0.92 g/cm 2 and 1.0 g/cm 2 , respectively. Assume that the oceans of the world cover an area, A , of about 3.62 × 10 8 km 2 and thatthe increase volume of theoceans can be calculated as A × h .

3. (a) Estimate the fractional change in the volume of Earth's oceans due to an average temperature change of 1°C.
(b) Use the fact that the average depth of the ocean is 4.00x10^3 m to estimate the change in depth. Note that βwater=2.07x10^-4 (°C) ^-1.
A sample of an ethanol-water solution has a volume of 54.4 cm^3 and a mass of 49.9 g. What is the percentage of ethanol (by mass) in the solution? (Assume that there is no change in volume when the pure compounds are mixed.) The density of ethanol is 0.789 g/cm^3 and that of water is 0.998 g/cm^3.
A 15.00 g sample of a solid substance is placed in 100.0 g of water at 25°C, and all of the solid dissolves. Then another 2.00 g of the substance is added, and all of it dissolves. A final 2.00 g is added, and none of it dissolves.
•Is the first solution saturated, unsaturated, or supersaturated?
•Is the second solution saturated, unsaturated, or supersaturated?
•What can you tell about the final solution that is in contact with the solid?
