A mixture of C3H8 and oxygen in 1L closed vessel has an internal pressure of 4 atm at 100ºC. When the mixture is ignited, the reaction produces CO2(g) and H2O(g) until all oxygen is consumed.
After the reaction, pressure of the vessel is 4.2 atm at the same temperature. Calculate the weight of oxygen present before the reaction. [Gas constant, R = 0.082 L atm mol–1 K–1].

A mixture of C3H8 and oxygen in 1L closed vessel has an internal press...
Given information:
- Mixture of C3H8 and oxygen in a 1L closed vessel
- Internal pressure of the mixture is 4 atm at 100°C
- Reaction produces CO2(g) and H2O(g) until all oxygen is consumed
- Pressure of the vessel after the reaction is 4.2 atm at the same temperature
- Gas constant, R = 0.082 L atm mol^-1 K^-1
Equation for the reaction:
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
Solution:
To find the weight of oxygen present before the reaction, we need to calculate the number of moles of oxygen before and after the reaction and then convert it to grams.
Step 1: Calculate the number of moles of oxygen before the reaction
We can use the ideal gas law to calculate the number of moles of oxygen before the reaction using the given information.
PV = nRT
Where:
P = pressure = 4 atm
V = volume = 1 L
n = number of moles of oxygen
R = gas constant = 0.082 L atm mol^-1 K^-1
T = temperature = 100°C = 373 K
Rearranging the equation, we can solve for n:
n = PV / RT
Substituting the values:
n = (4 atm)(1 L) / (0.082 L atm mol^-1 K^-1)(373 K)
Calculating, we get:
n = 0.129 moles
Step 2: Calculate the weight of oxygen before the reaction
To calculate the weight of oxygen, we need to use the molar mass of oxygen, which is 32 g/mol.
Weight = number of moles × molar mass
Weight = 0.129 moles × 32 g/mol
Calculating, we get:
Weight = 4.128 g
Therefore, the weight of oxygen present before the reaction is 4.128 grams.

Weight = number of moles × molar mass
Weight = 0.129 moles × 32 g/mol
Calculating, we get:
Weight = 4.128 g
Therefore, the weight of oxygen present before the reaction is 4.128 grams.
