What is the density of hydrogen?
Understand the Problem
The question is asking for the density of hydrogen, which is a physical property of the element that can be found in scientific literature or reliable online sources.
Answer
0.083 kg/m³
The density of gaseous hydrogen at 20°C and atmospheric pressure is 0.083 kg/m³.
Answer for screen readers
The density of gaseous hydrogen at 20°C and atmospheric pressure is 0.083 kg/m³.
More Information
Hydrogen has the lowest density of all gases, making it ideal for applications where mass needs to be minimized, such as in fuel for space exploration.
Tips
One common mistake is confusing density values at different temperatures or pressures. Always check and compare the conditions given with standard conditions.
