Answer:
The concentration of sulfuric acid in the flask is
Explanation:
The number of moles is mathematically defined as
For the number of moles of NaOH substituting 15.0mL = for volume and 0.25M for concentration we have
From the balanced equation we can that the number of moles of required for this reaction is
Concentration is mathematically defined as
Concentration of
Atomic mass Kr = 83.8 g/mole
Atomic mass Ar = 39.948 g/mole
So the ratio of the effusion rates = SQRT(83.8/39.948) = 1.45. Argon moves 45% faster than krypton!
