Answer to Question #301458 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 0₂ can fill the tank under the same pressure and temperature?

Answer 1

PV$=nRT$

$98×25=n×0.0821×(273.15+25)$

$n=100.09$

$Mass=\frac{32}{1000}×100.09$

$=3.2kg$
