Answer:
The rate of leakage will be higher for helium; its molecules move about 3 times faster than oxygen’s
Explanation:
Step 1: Data given
Molar mass helium = 4.0 g/mol
Molar mass O2 = 32 g/mol
Step 2: Graham's law
Graham's Law of Effusion states that the rate of effusion of a gas is inversely proportional to the square root of the molecular mass : 1/(Mr)^0.5
Rate of escape for He = 1/(4.0)^0.5 = 0.5
Rate of escape for O2 = 1/(32)^0.5 = 0.177
The rate of leakage will be higher for helium; its molecules move about 3 times faster than oxygen’s
Atoms with the same number of protons, but different numbers of neutrons are isotopes of the same element.
Answer:
Inversely
Explanation:
pV = k
When p increases, V must decrease for k to remain constant.
When V increases, p must decrease for k to remain constant.
When the product of two variables is a constant, they are inversely proportional to each other.
