What else can I help you with?
If an unknow gas diffuses 0.25 times as fast as Helium. What is the molecular mass of the unknown gas?
The rate of diffusion is inversely proportional to the square root of the molecular mass of the gas. Since the unknown gas diffuses 0.25 times as fast as helium, it means the square root of the molecular mass of the unknown gas is 4 times that of helium, thus the molecular mass of the unknown gas is 16 times that of helium, which is approximately 64 g/mol.
What is the abbreviation for gas helium?
The abbreviation for gas helium is He.
When gas cylider leak Which gas is evaporate in air from cylinder?
If it is already a gas, it does not need to evaporate.
What are you if you are gas with two protons in your nucleus?
If you are a gas with two protons in your nucleus, you are helium. Helium is a noble gas known for being lightweight and non-reactive.
What is the state of matter at room temperature of helium?
Helium is a colorless, odorless, tasteless and non-toxic gas at room temperature. It exists as a monatomic noble gas and is therefore inert and unreactive. It belongs to group 0 of the Periodic Table of Elements.
