A flexible container at an initial volume of 4.11 L contains 6.51 mol of gas. More gas is then added to the container until it reaches a final volume of 11.3 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.

The added mole will be "11.388 moles".

Explanation:

The given values are:

Initial volume,

V₁ = 4.11 L

Final volume,

V₂ = 11.3 L

Number of moles,

n₁ = 6.51

On applying Avogadro's law,

⇒  

On putting the estimated values, we get

⇒  

On applying cross-multiplication, we get

⇒  

⇒  

⇒  

⇒  

So that the number of moles at added gas will be:

thats how its supposed to be
