Answer to Question #302521 in General Chemistry for beb

Question

A 25.0 L tank contains 2.0 kg of neon gas with a pressure of 98.0 atm at 25°C. How many kilograms of O₂ can fill the tank under the same pressure and temperature?

Answer 1

At the same pressure and temperature;

Mass O2 / mass Ne = MW O2 / MW Ne

Mass O2 = mass Ne × (MW O2 / MW Ne)

mass O2 = 2kg × (31.998g/mol / 20.180g/mol)

mass O2 = 3.2kg

Kilograms of O2 that can fill the tank;

= 3.2kg
