Calculate the Mr of aspirin, next workout the percentage of H/aspirin
Answer:
Nuclear binding energy is the energy required to split am atoms nucleus into protons and neutrons.Mass effect is the difference between the predicted mass and the actual mass of an atoms nucleus. the binding energy of a system can appear as extra mass, which accounts for the difference.
Solution us here,
let the rate of diffusion of H2(r1) be x and⁷ the rate of diffusion of gas(r2) be x+x/6=7x/6.
Molar mass of H2 (M1)=2 g
Molar mass of gas(M2)= ?
Now, from the Ghram's law of diffusion of gas,

here, it looks like I have done wrong.
But all of the answers in option are wrong.
Because, rate of diffusion of any gas is inversely proportional to the square root of its malor mass.
And in the question, gas has higher rate of diffusion than hrdrogen. So it should have molar mass less than hydrogen.
