Answer : The volume of
will be, 514.11 ml
Explanation :
The balanced chemical reaction will be,

First we have to calculate the mass of
in tablet.

Now we have to calculate the moles of
.
Molar mass of
= 1 + 12 + 3(16) = 61 g/mole

Now we have to calculate the moles of
.
From the balanced chemical reaction, we conclude that
As, 1 mole of
react to give 1 mole of 
So, 0.0202 mole of
react to give 0.0202 mole of 
The moles of
= 0.0202 mole
Now we have to calculate the volume of
by using ideal gas equation.

where,
P = pressure of gas = 1.00 atm
V = volume of gas = ?
T = temperature of gas = 
n = number of moles of gas = 0.0202 mole
R = gas constant = 0.0821 L.atm/mole.K
Now put all the given values in the ideal gas equation, we get :


Therefore, the volume of
will be, 514.11 ml
