Answer : The number of moles of reacted was, 0.214 moles.
Explanation :
First we have to calculate the mole of gas.
Using ideal gas equation:
where,
P = Pressure of gas = 748 mmHg - 23.8 mHg = 724.2 mmHg = 0.953 atm (1 atm = 760 mmHg)
V = Volume of gas = 5.50 L
n = number of moles = ?
R = Gas constant =
T = Temperature of gas =
Putting values in above equation, we get:
Now we have to calculate the moles of
The balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 1 mole of gas produced from 1 mole of
So, 0.214 mole of gas produced from 0.214 mole of
Therefore, the number of moles of reacted was, 0.214 moles.
