The partial pressure of N2 in a mixture of gases, where the total pressure is 1.50 atm, is 300. torr. What is the mole fraction
makvit [3.9K]

Answer:

The mole fraction of N₂ is 0.26.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

PT = PA + PB

This relationship is due to the assumption that there are no attractive forces between the gases.

Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture. The mole fraction is a dimensionless quantity that expresses the ratio of the number of moles of a component to the number of moles of all the components present.

So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:

PA = XA * PT

In this case:

  • PA= PN₂= 300 torr
  • XA=XN₂= ?
  • PT= 1.50 atm= 1140 torr (being 1 atm= 760 torr)

Replacing:

300 torr= XN₂*1140 torr

Solving:

X_{N_{2} } =\frac{300 torr}{1140 torr}

XN₂= 0.26

<u><em>The mole fraction of N₂ is 0.26.</em></u>

A chemist performs the same tests on two homogeneous white crystalline solids, A and B. The results are shown in the table below
Nookie1986 [14]

Solid A contains only Covalent bonds and solid B only contains Ionic bonds. I know this because the appearance, solubility, and conductivity of solid A describes Covalent bonds.

Explanation:

Try this, but idk if it will be marked as correct.

How many moles of aluminum oxide will be formed from 17 moles of aluminum reaction?
Ainat [17]

Answer:

8.5 moles of Al₂O₃ will formed

Explanation:

Given data:

Number of moles of Al = 17 mol

Number of moles of Al₂O₃ formed = ?

Solution:

Chemical equation:

4Al  +  3O₂     →     2Al₂O₃

Now we will compare the moles of Al₂O₃  with Al.

                  Al            :            Al₂O₃      

                   4            :              2

                   17           :            2/4×17 = 8.5 mol

8.5 moles of Al₂O₃ will formed.
