''Astronomers have discovered some stars that seemingly orbit around an empty space. Astrometric binaries are relatively nearby stars which can be seen to wobble around a point in space, with no visible companion. The same mathematics used for ordinary binaries can be applied to infer the mass of the missing companion''

This question is based on Dalton's Law of Partial Pressure which states that "the total pressure of a system of gas is equal to the sum of the pressure of each individual gas (partial pressure).
Now, Partial Pressure of a gas = (mole fraction) × (total pressure)
⇒ Partial Pressure of Hydrogen =
×
= 0.31 atm
Thus the Partial Pressure of Hydrogen in the container is
0.31 atm.

Explanation:
The balanced reaction equation is given below:
+ → +
Mole fraction of CO2 to H20
= 8/10 =
Mole ratio of C4H10 to CO2 is 2:8 = 1:4
1 mole of n-butane - 38.12 g
4 moles - ?
= 152.48g fuel consumed.
