Some CO ₂ gas was kept in a sealed container at a pressure of 1 atm and at 273 K . This entire amount of CO ₂ gas was later passed through an aqueous solution of Ca ( OH )₂ . The excess unreacted Ca ( OH )₂ was later neutralized with 0.1 M of 40 mL HCl . If the volume of the sealed container of CO ₂ was x , then x is ________ cm ^3 (nearest integer). [Given : The entire amount of CO ₂( ~g ) reacted with exactly half

Correct answer

0

Step-by-step solution

Let moles of CO ₂= n moles of Ca ( OH )₂ total initially =2 n excess Ca ( OH )₂= n gm equivalent of Ca ( OH )₂= gm equivalent of HCl aligned & n 2=0.1 40 1000 1 & n =2 10⁻³ aligned Volume of CO ₂=2 10⁻³ 22400=44.8 ~cm ^3
