1.	Two vessels of capacities 1.5 litres and 2.0 litres containing hydrogen at 750 mm pressure and oxygen at 100 mm pressure respectively are connected to each other through a value. What will be the final pressure of the gaseous mixture assuming that temperature remains constant ?
Answer» SOLUTION :Final volume =1.5 L+2.0 L=3.5 L For partial pressure of `H_(2)`,`P_(1)V_(1)=P_(2)V_(2), i.e., 750xx1.5=P_(2)xx3.5` `p_(H_(2))=(750xx1.5)//3.5=321.43 mm` For partial pressure of `O_(2)``P_(1)'V_(1)'=P_(2)'V_(2)', i.e., 100xx2=P_(2)'xx3.5` or`p_(O_(2))=(100xx2)//3.5=57.14 mm` `P_("MIXTURE")=321.43+57.14 mm=378.57 mm`
