What is the pressure, in mm Hg, of 2.50 moles of an ideal gas if it has a volume of 50.0 liters when the temperature is 27.0° C?
svetlana [45]
Use the ideal gas law:
<em>PV=nRT
</em>p = pressure
v = volume
n = number of moles of sample
R = ideal gas constant = ~0.08206 (l*atm)/(K*mole)
T = Temp in Kelvin

Now we substitute while simultaneously solving for P(pressure)
P = (nRT)/V
P = (2.50 * 0.08206 * (27+273.15)) / 50
P = Now it's your turn.

makvit [3.9K]
<span>If a 2L bottle contains 27% juice, then the bottle contains about 0.54L of juice.
I assumed that, since most bottles contain 27% juice, that this would be no different.

27% of 2.00L, is 0.54L.</span>
