Mass =70 ( Mass of protons=1 ,Mass of neutrons =1, Mass of electron =0.0005(can be ignored))
Therefore, 40 +30=70
Charge= -2 ( it is taking in/attracting electrons to its shell) base on the proton number you are able to identify if it is attracting or releasing an electron, if the electron number is more than proton number then it is attracting therefore resulting in a negative charge vice versa for releasing an electron.
The partial pressure of argon in the atmosphere when the atmospheric pressure is 775. 0 torr is 7.75 torr.
Each gas that makes up a mixture of gases has a partial pressure, which represents the notional pressure of that gas if it were to occupy the entire volume of the initial mixture by itself at the same temperature.
The force that the weight of the atmosphere exerts on a certain area is known as atmospheric pressure.
As we know,
partial pressure is calculated as:
partial pressure = (total absolute pressure) × (volume fraction of gas component)
partial pressure = × 0.010
partial pressure = 775.0 × 0.010
partial pressure = 7.75 torr
Therefore, partial pressure of argon in the atmosphere when the atmospheric pressure is 775. 0 torr is 7.75 torr.
