a rigid container holds 22.4 l of an ideal gas at stp. how many ‘moles’ of gas need to be added to the container to make the pressure equal to 325 kpa?

mol

2.21

Explanation:

At STP, 1 mol of gas has a volume of 22.4 L, so we know we're starting with 1 mol of gas.

Assuming the temperature and volume are held constant, the number of moles needed to reach 325 kPa is found with ideal gas law:

PV = nRT

(325,000 Pa) (0.0224 m³) = n (8.314 Pa m³ / mol / K) (273.15 K)

n = 3.21 mol

Since we started with 1 mol, we need to add 2.21 mol.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
