5) A mixture of oxygen, hydrogen, and water vapor has a total pressure of
1.03 atm. The partial pressure of oxygen is 0.368 atm and that of hydrogen
is 0.100 atm. What is the partial pressure, atm, of water vapor?*

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
