Answer:<span>0.40 atm
How did we get 0.40?
Use the formula of Dalton's Law of partial pressure. </span>
Work it out by substituting the given values.
Given:
Total gas exerted by nitrogen- 80%
Total pressure- 2.0 atm
pressure of oxygen-?
P denotes total pressure exerted by nitrogen and n denotes total pressure of the mixture.
Poxygen = P/n
= 0.8 /2.0
= 0.4
(80 % is changed into decimal number, 0.8)
The scientist should do the following to make sure that their scientific investigation is replicable is by having to have their studies, researches and experiments to be written down as this will serve as a basis and a way of having to have a solid proof of having the investigation or experiment to be conducted again or to be replicable.
