The total pressure on the surface of Mars is variable day-to-day as it is on Earth. On a given day, it is 0.0068 atmospheres. The mole fractions of the top three components in the Martian atmosphere are constant and are 0.953 for CO2, 0.026 for N2, and 0.019 for Ar. In terms of torr the partial pressure of Ar on Mars is how many torr

0.098 torr

Explanation:

We know that the partial pressure is obtained as;

partial pressure = mole fraction * total pressure

Mole fraction for Ar = 0.019

Total pressure = 0.0068  atm

partial pressure of Ar = 0.019  * 0.0068  atm = 0.0001292 atm

since 1 atm = 760 torr

0.0001292 atm = 0.0001292 atm * 760/1 atm = 0.098 torr

i believe it is 40–40–20%
