Question 7 11 The density of an unknown gas is 3.24 g/L at 28 degrees Celsius and 1.00 atm. Find the molar mass of the gas. Hint: (n = grams/grams per mole), (density = mass/volume) (Molar Mass = grams/mole) 0 45.5 g/mol 80.1 g/mol 7.45 g/mol 086.3 g/mol Question 8 1 pts

80.0 g/mol.

Explanation:

The volume of a mole of gas at 28 degrees C and 1 atm = 301/273 * 22.4

= 24.7 litres.

So the molar mass = 24.7 * 3.24

= 80.0 g/mol.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
