Find out the ratio of the mass, Chemistry

1. For what fraction of annual CO2 emissions from fossil fuel burning are automobiles responsible?

2. A 1000-kg car travels 1.6 × 104 km/yr. What is the ratio of the mass of CO2 produced by fuel combustion to the mass of the car, if the car's fuel economy is:

A. 5.0 L/100 km

B. 7.5 L/100 km

C. 10 L/100 km

3. Calculate expected sea level rise for all possible combinations (shown in table below) of temperature increase and volume affected. Base your calculations on the following information and assumptions. Neatly lay out one example calculation; do not show all calculations. Present your calculated values neatly in the table.

1.    Total ocean volume is exactly 1.36 × 109 km3.

2.    Surface area of the oceans is exactly 3.61 × 108 km2.

3.    Initial mean temperature of the affected volume is 14oC.

4.    Density of sea water at various temperatures.

oC              Density, g/mL

14                    1.02512

15                    1.02500

16                    1.02483

17                    1.02466

18                    1.02449

1.    Assume that the temperature change is uniform throughout the entire volume under consideration.

2.    Assume that the surface area of the oceans does not change.
