Consider three flasks in diagram below. Assuming that connecting tube has negligible volume and all three falsks are at same temperature. If all three stopcocks are opened then select correct option(s):

Answer»

<P>`P_(HCl)=(2)/(3)`atm
`P_(NH_(3))=(1)/(3)` atm
`P_('total")=2` atm
`P_(He)=(5)/(3)` atm

Solution :`P_(He)=(5xx1)/(3)=(5)/(3)` atm
`P_(NH_(3)=0atm`
`P_(HCl)=(1)/(2)xx(2)/(3)=(1)/(3)` atm
`P_("total")=(5)/(3)+(!)/(3)=2atm`
