## How many moles of Na are in Na3PO4?

We do this by looking at the periodic table, which gives the molecular weight of every single element. The molecular weight tells you how many grams of that element makes up one mole of that element. In Na3PO4, there are 3 Na, 1 P, and 4 O.

## How many moles of Na+ ions are in 20 ml of 0.4 M Na3PO4?

So we have 0.024 moles of ions.

## How many sodium ions are in Na3PO4?

there are 3 sodium ions (Na⁺¹) are present, these are cations (+).

## How many moles are in Na+ ion?

Now, for every 1 mol of Na2 SO4 you have 2 moles of Na+ ions. Multiple the moles of Na2 SO4 that you found just then by 2 to obtain the moles of sodium ions. Use Avogadro’s number (6.022 x 1023 ) to find the number of ions present. (Recall that Avogrado’s number is the number of particles per mole of a substance).

5 moles Co2​

## How many sodium ions are present in 2 moles of sodium ions?

Answer: 1 molecule of Na3 PO 4 dissociates to give 3 sodium ions.

## How many moles of ions are present in 20cm3?

20cm3 means 0.02L or 0.02dm3. Therefore total Ca2+ ion in 20cm3 is… 0.05 = 0.001mole and total Cl- ion in 20cm3 solution is 0.002. hence total ions in he solution is 0.001+0.002 = 0.003.

## Why is sodium phosphate ionic?

Sodium Phosphate is an ionic compound formed by two ions, Sodium Na+ and Phosphate PO−34 . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take three +1 sodium ions to balance the one -3 phosphate ion.
