What is the density of H2 contain in a 2.75 l vessel at 850mmHg and 30.0*C?
What do we know?
We know volume: 2.75 L
We know temperature: 30.0 C
We know pressure: 850 mmHg
What do we want to find out? density
What is density? mass/volume
Since we already know volume, therefore, we must find out the mass of the H2 gas in this vessel.
Detailed, clear explanation of a physical chemistry problem, with useful conversions.
