The partial pressure of CH4(g) is 0.175 atm, and the partial pressure of O2(g) is 0.250 atm in a mixture of the two gases. The mixture occupies a volume of 10.5 L at 65 oC. Solve all three parts of the question. 1) The mole fraction of CH4(g) is , and the mole fraction of O2(g) is . 2) The total number of moles of gas in the mixture is . 3) There are grams of CH4(g) and grams of O2(g) in the mixture.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
