The number of moles of the gas when the volume changes to 20 L is 4.8 mol.
Explicación
## Step 1The problem involves the application of Avogadro's Law, which states that the volume of a gas is directly proportional to the number of moles of the gas, provided the temperature and pressure remain constant. This relationship can be represented by the formula:###
where
and
are the initial volume and number of moles, and
and
are the final volume and number of moles.## Step 2In this problem, we are given that the initial volume
is 25 L, the initial number of moles
is 6 mol, and the final volume
is 20 L. We are asked to find the final number of moles
.## Step 3We can rearrange the formula to solve for
:### \(n2 = (V2 * n1) / V1\)## Step 4Substitute the given values into the formula:### \(n2 = (20 * 6) / 25 = 4.8\)
