Agas of unknown molecular mass was allowed to effuse through a small opening under constant-pressure conditions. it required 120 s for 1.0 l of the gas to effuse. under identical experimental conditions it required 32 s for 1.0 l of o2 gas to effuse. you may want to reference (pages 416 - 419) section 10.8 while completing this problem. part a calculate the molar mass of the unknown gas. (remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 l; that is, rate and time are inversely proportional.)

450 g/mol

Explanation:

To solve the problem the problem, it is necessary to use Graham's Law of effusion

This answer is consistent with what we know. A heavier gas will require more time to effuse than a lighter gas

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
