The answer would be 1.86 x 10^4
Answer : The pressure of the gas is, 0.964 atm
Solution : Given,
Volume of gas = 9040 ml = 9.040 L (1 L = 1000 ml)
Moles of gas = 0.447 moles
Temperature of gas =

Using ideal gas equation,

where,
P = pressure of the gas
V = volume of the gas
T = temperature of the gas
n = number of moles of gas
R = gas constant = 
Now put all the given values in this formula, we get the pressure of the gas.

By rearranging the terms, we get

Therefore, the pressure of the gas is, 0.964 atm
Answer:
The percentage yield of the reaction = 73.6 %
Explanation:
Step 1: Data given
Mass of salicylic acid = 1.75 grams
the maximum possible yield = 1.93 g
The actual yield = 1.42 grams
Step 2: The balanced equation
C7H6O3 + CH3OH → C8H8O3 + H2O
Step 3: Calculate the percentage yield
Percentage yield = (actual yield / theoretical yield) * 100 %
Percentage yield = (1.42 grams / 1.93 grams ) * 100 %
Percentage yield = 73.6 %
The percentage yield of the reaction = 73.6 %
