Question

A 25.0 L tank contains 2.0 kg of neon gas with a pressure of 98.0 atm at . How many kilograms of can fill the tank under the same pressure and temperature?

Answer 1

Solution.

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

$n = \frac{m}{M}$

n = 100 mol

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

T = 298.73 K

$n1 = \frac{101325 \times 0.025}{8.31 \times 298.73}$

n1 = 1.02 mol

$m(Ne) = n \times M(Ne)$

m(Ne) = 0.02 kg

Answer:

m(Ne) = 0.02 kg
