Question

Hat will its volume be if an additional 0.25 mol of gas is added to the cylinder? (hint: the final number of moles is the sum of the initial number and the amount added.)

Answer 1

To find the final volume, add the initial moles of gas to the added moles of gas and use Avogadro's Law to calculate the final volume.

Step-by-step explanation:

To find the final volume, we need to calculate the final number of moles of gas. This can be done by adding the original number of moles to the moles of gas added. In this case, the final number of moles is 0.20 mol of hydrogen + 0.10 mol of oxygen + 0.25 mol of added gas = 0.55 mol. Next, we can use Avogadro's Law to solve for the final volume:

V1/n1 = V2/n2

Where V1 is the initial volume, n1 is the initial number of moles, V2 is the final volume, and n2 is the final number of moles. Solving for V2, we get:

V2 = (V1 * n2) / n1
