what is the pressure of the gas contained in each of the three boxes shown in the drawing?
Answer 1
For everyone: 1 atm = 760 mm Hg
Picture 1:
In other words: the pressure of the gas plus the pressure of a 52 cm column of mercury equals the pressure of the atmosphere.
P(gas) +(height Hg) = P(atm)
P(gas) = P(atm) – (Hg height) = 0.960 – (520/760) = 0.960 – 0.684 = 0.276 atm
(I divide 520 mm Hg into atm by dividing by 760)
Figure 2:
In other words: the pressure of the gas is the pressure exerted by a 67 mm column of mercury plus the pressure of the atmosphere
the pressure is (67/760) + 0.960 = 1.048 atm
Figure 3:
When the tube is closed, the gas pressure is equal to the height of the mercury column.
so 103/760 = 0.136 atm
answer 2
4 years later… We still have to do this for Mastering Chemistry lol
Here are the correct answers:
A) .31 ATM
B) 1.88ATM
C) 0.136ATM
