posledela3 years ago
3 0

Answer:

Mass of neon = 0.3 gram

Explanation:

Given:

Pressure = 842 torr

Temperature = 40.5°C = 313.5 K

Volume = 356 ml = 0.346 l

Find:

Mass of neon

Computation:

Gas constant R = 62.363

Number of mole = (842)(0.346)/(62.636)(313.5)

Number of mole = 0.015 (Approx)

Molar mass of neon is 20 g/ml

So,

Mass of neon = 20 x 0.015

Mass of neon = 0.3 gram
