How many moles are present 560.0 g of iron (lll) sulfate

xxMikexx [17]

Answer:

1.400 mol

Explanation:

To convert grams to moles, you will need the molar mass. The molar mass of iron(iii) sulfate is 399.88 g/mol. Divide grams by the molar mass to find moles.

(560.0 g)/(399.88 g/mol) = 1.400 mol

There are 1.400 mol present in 560.0 g of iron(iii) sulfate.

How many atoms of phosphorus are in 7.00 mol of copper(II) phosphate?

Rama09 [41]

<u>Answer:</u> The number of phosphorus atoms in given amount of copper(II) phosphate is $8.431\times 10^{24}$

<u>Explanation:</u>

We are given:

Moles of copper(II) phosphate $Cu_3(PO_4)_2$ = 7.00 mol

1 mole of copper(II) phosphate contains 3 moles of copper, 2 moles of phosphorus and 8 moles of oxygen atoms

Moles of phosphorus in copper(II) phosphate = $(2\times 7.00mol$

According to the mole concept:

1 mole of a compound contains $6.022\times 10^{23}$ number of particles

So, 7.00 moles of copper(II) phosphate will contain = $(2\times 7\times 6.022\times 10^{23}=8.431\times 10^{24}$ number of phosphorus atoms.

Hence, the number of phosphorus atoms in given amount of copper(II) phosphate is $8.431\times 10^{24}$
