The rate of effusion of a gas, r, is inversely proportional to the square root of its molar mass, m. the relative rate of two different gases is expressed as r1r2=m2m1−−−√ where r1 and r2 are the effusion rates of two gases and m1 and m2 are their respective molar masses. part a in an effusion experiment, it was determined that nitrogen gas, n2, effused at a rate 1.812 times faster than an unknown gas. what is the molar mass of the unknown gas? express your answer to four significant figures and include the appropriate units.

91.93 g/mol

Explanation:

According to the Graham's Law, the rate of effusion of a gas (r) is inversely proportional to the square root of its molar mass (M).

In an effusion experiment, it was determined that nitrogen gas, N₂, effused at a rate 1.812 times faster than an unknown gas X.

the movement of aircraft through clouds can even cause lightning strikes. a single lightning event is a "flash", which is a complex, multi-stage explosively ejected.

mark as brainliest

the dependant variable is spilled water

the independent is the heat
