Question

How many liters of radon gas would be in 3.43 moles at standard temperature and pressure (273 K and 100 kPa)?

A. 100 L
B. 76.83 L
C. 6.53 L
D. 6.99 L

Answer 1

Answer: Option B. 76.83L

Step-by-step explanation:

1 mole of a gas occupy 22.4L at stp. This implies that 1mole of Radon also occupy 22.4L at stp.

If 1 mole of Radon = 22.4L

Therefore, 3.43 moles of Radon = 3.43 x 22.4 = 76.83L
