Question

which conversion factor allows us to move between moles and gas volume at stp?
1 mole = 6.02 x 10²³ particles
1 mole = molar mass
1 mole = 22.4 l

Explanation:

To determine the conversion factor for moles and gas volume at STP (Standard Temperature and Pressure), we analyze each option:

• "1 mole = \(6.02 \times 10^{23}\) particles" is Avogadro's number, relating moles to number of particles, not volume.
• "1 mole = molar mass" relates moles to mass (in grams), not volume.
• At STP, 1 mole of any ideal gas occupies a volume of 22.4 liters. So "1 mole = 22.4 L" is the conversion factor for moles and gas volume at STP.

Answer:

1 mole = 22.4 L
