Answer to Question #223402 in General Chemistry for Mayoo

Question

What volume of air containing 21% of oxygen is required to completely burn 50g of sulfur containing 4% incombustible matter

Answer 1

Mass of sulfur =10050×4​=2

Mass of combustible matter$= 50-2 = 48$

$S+O_2--->SO_2$

$O_2= \frac{22.4×48}{32}=33.6$

Volume required$=\frac {100×33.6}{21}=160L$
