Amixture of 0.220 moles rn, 0.350 moles o2 and 0.640 moles ar has a total pressure of 2.95 atm. what is the pressure of o2? a mixture of 0.220 moles , 0.350 moles and 0.640 moles has a total pressure of 2.95 . what is the pressure of ? 0.649 atm 1.17 atm 0.853 atm 0.969 atm 1.03 atm

0.85 atm

Explanation:

We start by getting the total number of moles of all gases.

Total moles = 0.220 + 0.350 + 0.640 = 1.21 mol

Then we get the fraction of Oxygen moles and multiply by the total pressure;

The pressure of O2 = 0.350 mol / 1.21 mol x 2.95 atm  

                                = 0.85 atm

false

because it does not have the potential to be entirely used up

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
