Pv=nrt
Density is directly proportional to molar mass
Gas Density
n/v = p/rt
molar density * molar mass = density in grams in grams/liters
Molar Mass of Gas
Molar mass = mass (m) / moles (n)
Treat a mixture of gases as one gases.
Partial Pressure: The pressure of a single gas in a mixture of gases. Each gases acting independently of each other.
Dalton's Law of Partial Pressure
P^total= P1+ P2 + P3.....
P^number of gas = n^of moles (RT/v)
P of Oxygen gas = (RT/v) n of Oxygen Gas
4Fe(s) + 302(s) -> 2 Fe203
How many frams of water form when 1.24 L of H2 gass at STP compeltely reacts o2?
2H2 (g) + 02 (g) -> 2H20 (g)
V of H2= 1.24 L
P; 1.00 at
T; 273 k
n of h2 = Pv/rt = (1.0 atm)(1.24 L)/(0.0821)(273)
