Question

some oxygen gas occupies 11.3m3 at 97.2kpa and 76 centigrade. find its volume at 103 kpa and 21 centigrade

Answer 1

$\frac{P_1V_1}{T_1}$ = $\frac{P_2V_2}{T_2}$

P₁= 97.2kpa , V₁ = 11.3 m³ , T₁ = 76⁰C

P₂ = 103kpa , V₂ = ? , T₂ = 21⁰C

$\frac{97.2×11.3}{76}$ = $\frac{103×V_2}{21}$

$\frac{1098.36}{76}$ = $\frac{103×V_2}{21}$

V₂ = 2.94m³
