Current Question (ID: 8150)

Question:
$\text{Flask X is filled with 20 g of CH}_4\text{ gas at 100 }^\circ\text{C and another identical flask Y with 40 g O}_2\text{ gas at the same temperature. The correct statement among the following is -}$
Options:
  • 1. $\text{The pressure of the gases in the two flasks is identical}$
  • 2. $\text{The pressure of CH}_4\text{ in flask X is higher than that of O}_2\text{ in flask Y}$
  • 3. $\text{The pressure of CH}_4\text{ in flask X is lower than that of O}_2\text{ in flask Y}$
  • 4. $\text{The pressure of CH}_4\text{ in flask X is half that of O}_2\text{ in flask Y}$
Solution:
$\text{Hint: If the number of moles of gas in two flask are identical then pressure is also identical.}\n\n\text{Calculate the number of moles of CH}_4\text{ and O}_2\text{ as follows:}\n\n\text{n}_{\text{CH}_4} = \frac{20}{16} = \frac{5}{4}\n\n\text{n}_{\text{O}_2} = \frac{40}{32} = \frac{5}{4}\n\n\text{n}_{\text{CH}_4} = \text{n}_{\text{O}_2}\n\n\text{The number of moles of oxygen and methane gas are same hence, its pressure is also same.}$
