Answer:
72.22 g
Explanation:
975 mL Mercury× 13.5 g/mL = 72.22 g
Answer:
2.09 atm
Explanation:
We can solve this problem by using the equation of state for an ideal gas, which relates the pressure, the volume and the temperature of an ideal gas:

where
p is the pressure of the gas
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature
In this problem we have:
n = 0.65 mol is the number of moles of the gas
V = 8.0 L is the final volume of the gas
is the temperature of the gas
is the gas constant
Solving for p, we find the final pressure of the gas:
