At STP, 12.69g of noble gas occupies 14.09L. What is the identity of the noble gas?



Answer:
22.40 L·mol−1 / 14.09L * 12.69 g = 20.17 g·mol−1

Neon data: Standard atomic weight 20.1797(6)  g·mol−1

So the answer is • Ne •
Use the ideal gas law (PV=nRT) to figure it out! You can find n which will tell you what gas it is. (NOTE: STP means standard temperature and pressure)
