Question

Determine the number of moles of argon gas at STP, which occupies 56.2 liters.

Answer 1

Solution.

$$p \times V = n \times R \times T$$

$$n = \frac{p \times V}{R \times T}$$

p = 1.013*10^5 Pa

V = 22.4 l/mole

T = 273 K

$$n = \frac{1.013 \times 10^5 \times 22.4}{8.31 \times 273}$$

n = 1000.22 mole

Answer:

n = 1000.22 mole
