(2) Nitric acid is usually purchased in concentrated form with a 70.3% HNO3 concentration by mass and a density of 1.41 g/mL. HNO3 is strong electrolyte and CH3COOH is weak electrolyte. In chemical formula you may use: Any chemical element. Molecular weight calculation: 1.00794 + 14.0067 + 15.9994*3 The hybridization on the HNO3 is sp^3 because there are three bonds around the N which is your central atom in this compound so it would be sp^3. The N atom is sp² hybridized. Write the balanced molecular, complete ionic, and net ionic equations for each of the following acid-base reactions. The N atom has steric number SN = 3. Indicate the multiplication of units explicitly either with a multiplication dot or a dash. ››HNO3 molecular weight. 1 Approved Answer. Express its concentration in (a) molality (b) in Molarity (c) how many ml of this solution is needed to prepare 250. mL of 1.00 M HNO3? The O bonded to H has SN = 4 (two bonding pairs and two lone pairs). HNO3 is a strong acid. After bonding, there are six hybrid orbitals in HNO₃. For this equation HNO3(aq) + Al(OH)3(s) →...? NaCH3COO(aq)+HNO3(aq)----->NaNO3(aq)+CHOOH(aq . Molar mass of HNO3 = 63.01284 g/mol This compound is also known as Nitric Acid.. Make sure you express your answer in the correct number of significant digits. Convert grams HNO3 to moles or moles HNO3 to grams. Express your answer as a chemical equation. Include states-of-matter under SATP conditions in your answer.) HNO3 Express your answers as ions separated by a comma.
