  • question_answer
                    At \[{{25}^{\text{o}}}C\] and 730 mm pressure, 380 mL of dry oxygen was collected. If the temperature is constant, what volume will the oxygen occupy at 760 mm pressure?                                                                      

    A)              365 mL    

    B)              2 g                            

    C)              10 g          

    D)              20 g

    Correct Answer: A

    Solution :

                    As the temperature is constant. Boyle?s law is applicable ?                 \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\]                 \[{{V}_{1}}=380\,mL,{{P}_{1}}=730\,mm,{{V}_{2}}=?\]                 \[{{P}_{2}}=760\,mm\]                 \[730\times 380=760\times {{V}_{2}}\]                 \[{{V}_{2}}=\frac{730\times 380}{760}\]             = 365 mL
