Question

a unknown gas diffuses at a rate of 0.5 time the rate of nitrogen at the same temperature and pressure. calculate the molar mass of the unknown gas

Answer 1

Answer:

Explanation:

Runkown /RN2 = ✓(28/unknown)

or(0.5)^2 = 28/unknown

Or, 0.25 = 28/Munknown

Munknown = 28/0.25

= 112 g/mol
