a mixture of gases at atmosphere contain 65%ofnitrogen, 15%ofcarbon dioxide and 20%of oxygen by volume. what is the partial pressure in the atmosphere?

A mixture of gases at 760 mm pressure contains 65% nitrogen 15% oxygen and 20% carbon dioxide by volume What is partial pressure of each in mm ? . ∴P′CO2=760×20100=152mm .

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

1. they vary with a higher number because boiling is way hotter than melting
