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
