Question

16 g of oxygen and 3 g of hydrogen are mixed and kept at 760 mm pressure and . The total volume occupied by the mixture will be nearly.

• A. 22.4 litres
• B. 33.6 litres
• C. 448 litres
• D. 44800 ml

Answer 1

Answer: (D)

44800 ml

Answer 2

n of

n of $H _ { 2 } = \frac { 3 } { 2 }$

Total no. of moles = $\frac { 3 } { 2 } + \frac { 1 } { 2 } = 2$

$V = \frac { n R T } { P } = \frac { 2 \times .082 \times 273 } { 1 } = 44.8 \mathrm { lit }$ = 44800 ml
