To determine the volume in liters of 2.00 mol of S2 gas at STP, you would use _______ as a conversion factor.

22.4 L/mol

To determine the volume in liters of 2.00 mol of S2 gas at STP, you would use the conversion factor of 22.4 L/mol.

To understand why this is the correct conversion factor, we first look at the relationship between moles and volume for an ideal gas at standard temperature and pressure (STP). STP is defined as a temperature of 0 degrees Celsius (273.15 Kelvin) and a pressure of 1 atmosphere (atm).

According to the ideal gas law, the volume of a gas is directly proportional to the number of moles of the gas at constant temperature and pressure. This relationship can be expressed as:

V = n * Vm

Where:
V is the volume of the gas in liters
n is the number of moles of the gas
Vm is the molar volume, which is the volume occupied by one mole of gas at STP

The molar volume at STP is known to be 22.4 liters/mol for ideal gases. Therefore, to convert moles to liters at STP, we can multiply the number of moles by the molar volume:

V = n * Vm
V = 2.00 mol * 22.4 L/mol
V = 44.8 L

Hence, to determine the volume in liters of 2.00 mol of S2 gas at STP, you would use the conversion factor of 22.4 L/mol.
