Asample of co2 is collected over water at 23oc. if the total pressure of the sample is 734 torr, and the vapor pressure of water at 23oc is 21.2 torr, what is the partial pressure of co2 in torr? don"t write the units: only the values.

The partial pressure of CO2 is 712,8 in torr

Explanation:

Molar fraction = Pressure in a compound / Total Pressure

Molar fraction H20 = 21,2 / 734 = 0,0288

Sum of molar fraction in a sample = 1

1 - 0,0288 = 0,9712 (molar fraction of CO2)

Molar fraction CO2 = Pressure CO2 / Total pressure

0,9712 . 734 = Pressure CO2

712,8 =Pressure CO2

a corroding iron, if that's one of your choices

i wish i could but this one is weird give me abc and i can solve it.
