A compound made up of two elements A and B has A=70%, B=30%. Their relative number of moles in the compound are 1.25 and 1.88. Calculate atomic masses of the elements A and B |
|
Answer» SOLUTION :`"Relative no. of moles of an ELEMENT"=(%" of the element")/("Atomic MASS") or "Atomic mass"=(%" of the element")/("Relative no. of moles")` `THEREFORE"Atomic mass of A"=(70)/(1.25)=56,"Atomic mass of B"=(30)/(1.88)=16` |
