In the sulphur estimation,

0 . 471g

of an organic compound gave

1 . 44g

of barium sulfate. The percentage of sulphur in the compound is. (Nearest integer) (Atomic Mass of

Ba = 137u

)

Correct answer

0

Step-by-step solution

$233g$ of ${BaSO}_{4}$ contains $32g$ sulphur.

Amount of $S$ in $1 . 44g$ of ${BaSO}_{4} = \dfrac{32}{233} \times 1 . 44$

So percentage of $S$ in $0 . 471$ of organic compound $= \dfrac{32}{233} \times \dfrac{1 . 44}{0 . 471} \times 100 = 42 %$
