To determine what gas is this, we use Graham's Law of Effusion where it relates the rates of effusion of gases and their molar masses. We do as follows:
r1/r2 = √(M2 / M1)
Let 1 be the the unkown gas and 2 the H2 gas.
r1/r2 = 0.225
M2 = 2.02 g/mol
0.225 = √(2.02 / M1)
M1 = 39.90 g/mol
From the periodic table of elements, most likely, the gas is argon.
The closer the atoms are the more the nitrogen will be come bigger or the oppisite
Answer : The number of servings of this potato chips eaten to consume 0.0230 moles of NaCl must be, 5.39
Explanation :
First we have to calculate the moles of NaCl.


Now we have to calculate the number of servings.
As, the number of serving in 0.004269 moles of NaCl = 1 serving
So, the number of serving in 0.0230 moles of NaCl =
serving
Thus, the number of servings of this potato chips eaten to consume 0.0230 moles of NaCl must be, 5.39
