A steel tank contains 302 g of ammonia gs (NH3 with molar mass 17.0 g/mol) at a pressure of 1.67 x 106 and a temperature of 88.0oC. (a) What is the volume of the tank in liters? (b) Later the temperature is 80.7oC and the pressure is 1.12 x 106 Pa. How many grams of gas have leaked out of the tank? (Ignore the thermal contraction of the tank.)
Determine the direction of your displacement vector. Express your answer as an angle relative to east.

An object is under the force F = (k1*x) i - (k2*y) j. Calculate the work done by this force when the object: moves on the x-axis from the origin to the point (a,0), and then goes from (a,0) until (a,b) parallel to the y-axis.
