Explain the relationship between the rate of effusion of a gas and its molar mass. methane gas (ch4) effuses 3.4 times faster than an unknown gas. determine the molar mass of the unknown gas. show your work or explain your answer, giving specific values used to determine the answer.

Answer : The molar mass of unknown gas is 184.96 g/mole.

Solution : Given,

Effusion rate of methane gas is 3.4 times faster than an unknown gas. That means,

Molar mass of methane, = 16 g/mole

According to Graham's law of effusion, the rate of effusion of a gas in inversely proportional to the square root of the mass of a gas.

where,

R = rate of effusion of a gas

M = Molar mass of a gas

By rearranging the above formula, we get

Now put all the given values in this formula, we get molar mass of unknown gas.

Therefore, the molar mass of unknown gas is 184.96 g/mole.

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
