Question

What is the density of oxygen gas at ntp?

Answer 1

Answer:

1.429 g/litre

Explanation:

The density of oxygen at ntp is 1.429 g/litre

Answer 2

Answer:

At NTP, P = 1 atm, and T = 293.15 K  

In the ideal gas law, n can be express as mass / MW. Density is mass/V. Substituting into PV=nRT and rearranging gives:  

PV = (mass/MW) RT  

Mass/V = P(MW) / RT  

So,  

Mass/V = density = 1 atm (32.0 g/mol) / (0.0821 Latm/molK X 293.15)  

Density = 1.33 g/L
