% text sulphur =(32/233) × ( text weight of BaSO 4 text formed / text weight of organic compound ) × 100 =(32/233) × (1.4439/0.471) × 100 =42.10 Nearest integer 42

Q. In sulphur estimation, $0.471 g$ of an organic compound gave $1.4439 g$ of barium sulphate. The percentage of sulphur in the compound is ___(Nearest Integer) (Grven: Atomic mass Ba: $137 u, S : 32 u, O : 16 u$ )

$% sulphur = \frac{32}{233} \times \frac{weight of B a S O _{4} formed}{weight of organic compound} \times 100$
$= \frac{32}{233} \times \frac{1.4439}{0.471} \times 100$
$= 42.10$
Nearest integer 42
