AB_(2) andA_(2)B_(3) are two compounds of the elements A and B 0.15 mole of each of these compounds weights 9.3and 15.9g respectively. Find the atomic masses of A and B. |
|
Answer» Solution :LET atomic masses of A and B be 'a' and 'b' respectively. `THEREFORE 0.15(a+2b)=9.3g` 0.15(2a+3b)=15.9g i.e., a+2b=62 On SOLVING EQUATIONS (i) and (ii) b=18 and a=26 |
