How many atoms of each element are in 4na3po4? a. 3 sodium, 1 phosphorus, 4 oxygen b. 4 sodium, 4 phosphorus, 4 oxygen c. 12 sodium, 1 phosphorus, 4 oxygen d. 12 sodium, 4 phosphorus, 16 oxygen

Answers

I took this quiz and the correct answer is not A.

4Na3PO4 The 4 at the beginning of the formula is important, it means you multiply everything after it by 4 so you would instead get the answer,

D. 12 Sodium, 4 phosphorus, 16 oxygen

One mole of Na_{3}PO_{4} consist of three atoms of sodium, one atom of phosphorus and four atoms of oxygen.

Now, according to question four moles of Na_{3}PO_{4} is present. Therefore, every element present in the compound is multilply by four with their number of atoms in the compound.

So, Number of atoms of sodium in four moles of Na_{3}PO_{4} is 3times 4 = 12 atoms of sodium.

Number of atoms of phosphorus in four moles of Na_{3}PO_{4} is 1times 4 = 4 atoms of  phosphorus.

Number of atoms of oxygen in four moles of Na_{3}PO_{4} is 4times 4 = 16 atoms of oxygen.

Hence, number of atoms of sodium is 12 , number of atoms of phosphorus is 4 and number of atoms of oxygen is 16

Thus, option (D) is the correct answer.
