There are 3.01 moles. round to 3 if it asks for a whole number
For a single atom, the charge is the number of protons minus the number of electrons
According of Dalton's law of Partial pressure, the total pressure of a mixture of gases is the sum of the partial pressures of the individual vases in the mixture.
Hence;
The for hydrogen collected over water, we have a mixture of hydrogen gas and water vapour.
Total pressure = pressure of hydrogen gas + vapour pressure of water
Pressure of hydrogen gas = Total pressure - vapour pressure of water
Pressure of hydrogen gas = 636 mmHg - 28.3 mmHg
Pressure of hydrogen gas = 607.7 mmHg
Some people may say the python is not that big of an issue,but when they see how much of a disaster the release of the python can cause,they would probably stop trying to challenge this idea
