What is the molarity of 10% w by V of HNO3 solution?

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.

How many ions are in 1 mole of NaCl?

1 Expert Answer

Sodium chloride is NaCl. It is made up of sodium ions (Na+) and chloride ions (Cl). 1 mole of sodium chloride contains 1 mole Na+ and 1 mole Cl, so there are TWO moles of ions for every 1 mole of NaCl.
