Two oxides of metals A and B are isomorphous . The metal A whose atomic mass is 52, forms a chloride whose vapour density is 79. the oxide of the metal B contains 47.1% oxygen. Calculate the atomic mass of B. |

Answer» SOLUTION :Let the VALENCY of A be X. the FORMULA of chloride`=Acl_(x)` 2 V.D.`=A+x xx35.5` or x=3 As the two oxides are isomorphous, the valency of B is also 3. Equivalent mass of `B=(52.9)/(47.1)xx8=8.99`. Atomic mass of `B=8.99xx3=26.97`. |
