Answer: 54.2\times 10^{23} atoms

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here copper is having an oxidation state of +2 called as Cu^{2+} cation and phosphate PO_4^{3-} is an anion with oxidation state of -3. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral Cu_3(PO_4)_2.

1 mole of Cu_3(PO_4)_2 contains = 2\times 6.023\times 10^{23}=12.05\times 10^{23} atoms of phosphorous

Thus 4.50 mole of Cu_3(PO_4)_2 contain = \frac{12.05\times 10^{23}}{1}\times 4.50=54.2\times 10^{23} atomsof phosphorous

Thus there are 54.2\times 10^{23} atoms of phosphorous.

<span>Because copper (II) cations have a charge of +2 and phosphate anions have a charge of -3, the formula of anhydrous* copper (II) phosphate is

Cu3(PO4)2

This shows that each formula unit contains 2 atoms of phosphorus. Therefore, the atoms of phosphorus in 4.8 formula units is

4.8 x Avogadro's Number (</span><span>6.022x10*23)</span>, or about 2.9 X 10*24 atoms

If 1.0 mole of neon, 2.0 moles of helium, and 3.0 moles of argon are mixed, what is the mole fraction of helium?
alexandr1967 [171]

The mole fraction of helium is 0.33.

The mole fraction can be calculated with the aid of dividing the number of moles of 1 factor of an answer by means of the overall number of moles of all the additives of a solution. it's far noted that the sum of the mole fraction of all the components in the solution should be same to one.

Mole fraction is a unit of attention. within the answer, the relative amount of solute and solvents are measured by the mole fraction and it is represented. The mole fraction is the wide variety of moles of a specific thing within the solution divided by way of the entire wide variety of moles.

Mole fraction represents the quantity of molecules of a selected thing in a combination divided by using the total variety of moles within the given mixture. it is a manner of expressing the concentration of a solution. consequently, the sum of mole fraction of all of the additives is always equal to one.

Mole of neon = 1

mole of helium = 2

mole of argon = 3

Total mole = 1 + 2 + 3 = 6

Mole fraction = mole of helium / total mole

                      =  2 / 6 = 0.33
