With 10% nitric acid, 0.1 x 1500 gm/L = 150 gm/L. We know Molar mass of HNO3 = 63.01 g/mol.

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

a) 2 moles of sodium phosphate.

ANSWER: 36.12 x 1023 Na ions, which isn’t in correct Scientific Notation OR Sig Figs, so,… = 4 x 1024 Na ions NOTE: your book includes 2 sig figs.

## How do you find 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).

## What ions are present in a solution of Na3PO4?

Answer and Explanation: The ions present in Na3 PO4 are Na+ and PO4 3-. Sodium is found in the alkali metals on the periodic table, which indicates it will form a +1 charge in solution. The phosphate ion is an example of a polyatomic ion, whose charge must be memorized.

## How many moles of Na are in NaCl?

If I take NaCl as a molecule, then there are 2 Na atoms and 2 Cl atoms in both sides or one Na atom and 0.5 Cl atom in both sides. If I take NaCl a mole of molecules, then there are 2 moles of Na and 2 moles of Cl₂ molecules in both sides or 1 mole of Na and 0. s moles of Cl₂ molecules present.

## How many moles are in an ion?

Of particles i.e. ion,atom, subatomic particle present in one mole of any substance is always equal to avogadro number I.e. equal to 6.023*10^23. So the no. Of na+ or cl- ion is 6.023*10^23.
