Which gas sample has the greatest volume at STP?
- A. 10.0 g Kr
- B. 10.0 g Xe
- C. 10.0 g He
A mole or molecule of gas, in similar conditions in terms of temperature and pressure has the same volume. In the normal condition (t = 100C, P = 1 atm) the volume of all gases in molar are equivalent to 22.4 Liters. Formula: Determine the mole of gas for the given gas’s volume at normal conditions The formula is: n = V/22.4 Calculate the gas volume under normal conditions, given the mole count V = nx22.4 (litres) In there: + N: mole count in gas (mol) + V: the volume of gas under normal conditions (liters)
Correct answer: C
