In a mixture of 1.75 moles of gas, 0.75 moles are nitrogen molecules. what is the mole fraction of nitrogen in this mixture?

Given:

Total moles of the gas mixture = 1.75

Moles of Nitrogen gas in the mixture = 0.75

To determine:

Moles fraction of nitrogen

Explanation:

Mole fraction of a particular element in a mixture is given by the ratio of the number of moles of that element by the total number of moles

In this case-

Moles fraction of N2 = moles of N2/total number of moles

                                 = 0.75/1.75 = 0.429

Ans: Mole fraction of N2 in the gas mixture is 0.429 (or) 0.43.    

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

the answer is true. hope it .
