Answer:
The partial pressure is 
Explanation:
The Partial pressure of 
is mathematically represented as
Where 
is the total pressure of water with a value of 15.5 mm of Hg
is the partial pressure of water with a value 753 mm of Hg
Now substituting values
Answer:
The SI base unit for amount of substance is the mole. one mole is equal to one mole potassium bromide or 119.0023 grams

Assume ideal gas behavior, then solve for the total number of moles:
PV = nRT
(5.50 atm)(10 L) = n(0.0821 L-atm/mol-K)(23+273 K)
n = 2.263 mol
Moles methane: 8 g ÷ 16.04 g/mol = 0.499 mol
Moles ethane: 18 g ÷ 30.07 g/mol = 0.599 mol
Moles propane: 2.263 - (0.499+0.599) = 1.165 mol
Applying Raoult's Law:
Partial pressure = Mole fraction * Total Pressure
<em>Partial Pressure of Methane = (0.499/2.263)(5.5 atm) = 1.21 atm</em>
<em>Partial Pressure of Ethane = (0.599/2.263)(5.5 atm) = 1.46 atm</em>
<em>Partial Pressure of Propane = (1.165/2.263)(5.5 atm) = 2.83 atm</em>
