What is the partial pressure of O2g in a mixture of gases consisting of 2.50 g of O2 and 6.40 g of Heg if the total pressure of this mixture is 8.25 ATM?

Moles of O2=2.5/32=0.078125 Moles of He=6.4/4=1.6 Mole fraction of O2=0.078125/(0.078125+1.6)=0.046555 Partial pressure of O2=0.046555 x 8.25=0.384atm


What is the partial pressure of 20.84 percent of O2 in air?

The partial pressure of a gas in a mixture is equal to the total pressure of the mixture multiplied by the mole fraction of that gas. Since the mole fraction of O2 in air is 0.2084 and the total pressure of air is approximately 1 atmosphere, the partial pressure of O2 in air is approximately 0.2084 atmosphere.

Chemistry Balance H2 O2----H2O?

you can never balance the equation because there will always be too few oxygen atoms in the first molecule if the hydrogens are balanced That answer is incorrect. The balanced equation is as follows: 2H2O2 ---> 2H2O + O2 You begin with 4 hydrogen and 4 oxygen, and end with 4 hydrogen and 4 oxygen.
