A gas `(1 g)` at `4` bar pressure. If we add `2 gm` of gas `B` then the total pressure inside the container is `6` bar. Which of the following is true?

A

`M_(A)=2M_B`

B

`M_(B)=2M_A`

C

`M_A=4M_B`

D

`M_B=4M_A`

Text Solution

Verified by Experts

The correct Answer is:
A
`(n_(1))/(p_(1))=(n_(2))/(p_(2))`
`((1)/(M_(A)))/(4)=((1)/(M_(A))+(2)/(M_(B)))/(6)`
`(1)/(M_(A))=(4)/(M_(B))`
`M_(B)=4M_(A)`

A manometer is connected to a gas containing bulb. The open arm reads 43.7 cm whereas the arm connected to the bulb reads 15.6 cm . If the barometric pressure is 743 mm mercury , calculate the pressure of the gas in bar? Strategy : The pressure of the gas inside the bulb is greater than the external atmospheric pressure because the height of mercury column in the left arm is less than in the right arm.Therefore , p_("gas") ("in cm") = p_("atom") ("in cm") + h cm
