The correct steps to solve this problem are: Use Avogadro's number to convert from molecules to moles, Convert from moles to Liters using \(22.4L=1\) mol as conversion factor.
Explicar
## Step 1: <br />The first step in solving this problem is to convert the number of molecules to moles. This is done using Avogadro's number, which states that there are \(6.022 \times 10^{23}\) molecules in one mole. <br /><br />### \(Number\, of\, moles = \frac{Number\, of\, molecules}{Avogadro's\, number}\)<br /><br />## Step 2: <br />Once we have the number of moles, we can then convert this to liters using the conversion factor \(22.4L = 1\) mol. This is because at standard temperature and pressure (STP), one mole of any gas occupies 22.4 liters.<br /><br />### \(Volume\, in\, liters = Number\, of\, moles \times 22.4L/mol\)
