If the quantity of oxygen occupying 2.71 container at a pressure of 0.825 atmospheres and 300K is reduced by one half, what is the pressure exerted by the remaining gas?
- A) 1.650atm
- B) 0.825atm
- C) 0.413atm
- D) 0.275atm
Correct Answer: D) 0.275atm
Explanation
\(V_1 = 2.71\), \(P_1 = 0.825\)atm, \(T = 300K\)\(V_2 = \cfrac{2.71}{2}, P_2 = ?\)From, ideal gas equation:\(\cfrac{P_1V_1}{P_2V_2} = \cfrac{T_1}{T_2} = \cfrac{0.825 \times 2.7}{P_2 \times (2.7 \div 2)} = \cfrac{300}{273}\)\(P_2 = \cfrac{0.825 \times 2.7 \times 273}{300 \times (2.7 \div 2)} = 1.5015\)atmPost an Explanation Or Report an Error
