000 atm of dry nitrogen, placed in a container having a pinhole opening in its side, leaks from the container 3.55 times faster
Ivanshal [37]
We will assume that the question is discussing 1.000 atm of N₂ initially. The question is discussing diffusion rates of two gases and asks us to identify the species. We can use Graham's Law to attempt this problem with the following formula:

Rate₁/Rate₂ = sqrt(M₂/M₁)

We are told that the N₂ is 3.55 times as fast as the unknown species, so rate 1 = 3.55 and rate 2 = 1. We know the molecular weight of N₂ as 28 g/mol. Now we can use the equation above to solve for the molecular weight of the unknown, M₂:

3.55/1 = sqrt(M2/28)
(3.55)² = M₂/28
M₂ = 28 (3.55)₂
M₂ = 353 g/mol

The unknown compound has a molecular mass of roughly 353 g/mol and this is very close to the molecular mass of UF₆ which is 352.02 g/mol. Therefore, it is likely that the unknown gas is UF₆.

A flask with a volume of 250.0 mL contains air with a density of 1.211 g/L. What is the mass of the air contained in the flask?
labwork [276]
250.0 mL in liters:

250.0 / 1000 => 0.25 L

D = m / V

1.211 = m / 0.25

m = 1.211 x 0.25

m = 0.30275 g
