Question

In sulphur estimation, $0471 \,g$ of an organic compound gave $14439 \,g$ of barium sulphate The percentage of sulphur in the compound is ___(Nearest Integer) (Grven: Atomic mass Ba: $137 \,u , S : 32\, u , O : 16 \,u$ )

Answer 1

The correct answer is 42.
% sulphur =23332​× weight of organic compound weight of BaSO4​ formed ​×100
=23332​×0.4711.4439​×100
=42.10
Nearest integer 42
