Question

How many moles are in 9.8 L of xenon gas?

Answer 1

0.4375 moles

Step-by-step explanation:

At standard temperature and pressure one mole of ideal gas occupies 22.4 L of volume.

Hence we can write following relation,

22.4 L volume is occupied by = 1 mole of Gas

So,

9.8 L of Volume will be occupied by = X mole of Gas

Solving for X,

X = 1 mole × 9.8 L / 22.4 L

X = 0.4375 moles
