People who ascend high altitudes experience Delton’s law when they try to breathe. Oxygen’s pressure decreases a total atmospheric pressure decreases in accordance with Dalton’s law.

then you can say
concentration = M*1000/V
No He believed tiny particles were invisible and couldn't be changed....So No The person that believed in this was Dalton .
