Dalton's law equation is used to find what?
the density of a pure gas
the total pressure of a pure gas
the total pressure of a gas mixture
the volume of a gas mixture
What is the total pressure of the heliox gas in the diagram?
300 kPa
100 kPa
400 kPa
500 kPa
In a mixture of gases, each gas contributes to the total pressure. The individual contribution of each gas is known as the _________________.
partial volume
partial pressure
molar mass
mole ratio
Which equation represents Dalton's Law?
E = mc2
PV = nRT
P1 / T1 = P2 / T2
Ptotal = P1 + P2 + P3
A mixture of H, Ne, & O has a pressure of 12.4 atm. If Hydrogen measures 5.6 atm and Oxygen measures 2.0 atm, what is the pressure of Neon?
7.6 L
4.8 L
5.4 L
12.0 L
Dalton's Law states that
At a constant temperature, the volume of a confined ideal gas varies inversely with its pressure
The total pressure of a mixture of gases is equal to the sum of the partial pressures of each gas
Gases tend to expand when heated
The density of an ideal gas at constant pressure varies inversely with the absolute temperature of the gas
