Answer:
a) The number density is 3.623 × 10⁻³
The mass of the atmosphere is 1.3 × 10²²Kg
b) The pressure is 10⁻²⁰ Millimeter of mercury
c) The mass mixing ratio is 0.0107
The partial pressure of ethane is 0.01114 Pa
Yes it is condensable because it boiling point is -88.5 C which is equivalent to 184.5 K i.e is adding 273 to -88.5C and the temperature of the atmosphere is 37 K.

The two cars have same momentum
Explanation:
The momentum of an object is given by the equation
where
m is the mass of the object
v is its velocity
For the car A in this problem,
m = 5 kg
v = 10 m/s
So its momentum is
For car B we have,
m = 10 kg
v = 5 m/s
So its momentum is
Therefore, the two cars have same momentum.
