Explanation:
A 25.00 ml sample of hydrochloric acid solution, HCl, is titrated with 0.0512 m NaOH solution. the volume of NaOH solution required is 21.68 ml then the molarity of the HCl solution is 0.044 M .
Calculation ,
Formula used :
...( i )
Where M is the molarity or concentration and V is the volume in ml .
concentration of hydrochloric acid solution (
) = ?
concentration of NaOH (
) = 0.0512 M
volume of hydrochloric acid solution (
) = 25.00 ml
volume of NaOH (
) = 21.68 ml
Putting the value of concentration , volume of both in equation ( i ) we get .
× 25.00 ml = 0.0512 × 21.68 ml
= 0.0512 × 21.68 ml / 25.00 ml= 0.044 M

The stoichiometry of the reaction is 5 mols of O2 produces 4 mols of CO2.
1 mol at STP is equivalent to 22.4 liters.
So, 5*22.4 liters of O2 produces 4*22.44 liters of CO2
Then 60 liters of O2 produces 60*4/5 = 48 liters of CO2
