what is the volume of 1.00 mol of gas at STP? what is the signifacance of this number?
- 1 decade agoFavorite Answer
STP corresponds to 273 K (0° Celsius) and 1 atm
so PV = nRT
remember R us the gas constant: 0.0821 liter·atm/mol·K
1(atm)(V) = (1mol)(0.0821 liter·atm/mol·K )(273 K)
V = 22.4133 Liters
you need to round volume to 3 significant figures
V = 22.4 L
Next time put this in the chemistry section :P

To solve, plug in the appropriate values into the ideal gas law, PV=nRT.
This is the volume of one mole of ANY gas at STP, due to Avogadro's Law.
