The answer is 1804.03961. Let’s say you are converting between CU (No3) 2 grams and moles. You can see more details about each unit of measurement: The molecular weight of CU (No3) 2 or the mole SI base unit for the amount of substance is the mole.
Percent Composition by Element
This means that the molecular mass of a substance is the mass (in grams per mole) of 6.022 × 1023 atoms, molecules or formula units of the substance.
It is a lead atom, 2 nitrogen atoms and 4 oxygen atoms.
The nitrate anion is a monovalent polyatomic ion (1 charge) consisting of a single nitrogen atom ionically bonded to three oxygen atoms (symbol: NO3) for a total formula weight of 62.05. Lead nitrate is generally readily available in most quantities.
Lead nitrate standard solution, dissolve 33.0 g of lead nitrate Pb (NO3) 2 in 0.5% v / v nitric acid and dilute to 1 liter with 0.5% nitric acid. This solution contains 20.36 mg of Pb per ml. The exact lead content can, if necessary, be determined by titration with EDTA.
The pH value of the crude aqueous solution of lead nitrate is 12, adjust with ammonia until the turbidity phenomenon no longer disappears, the pH value at this point is 34. The Pb n.
S135: Chemical Rxns - Precipitation - Pb (NO3) 2 + KI → PbI2 (s) A 100 mm Petri dish with water is placed on an overhead projector. If the solid Pb (NO3) 2 is placed on one side and the solid KI on the other, the PbI2 in the middle will fail.

Metallic lead is an element with the atomic symbol Pb, atomic number 82 and atomic weight 207.2. Lead (0) is a simple lead. It plays a role as a neurotoxin.
Answer: The name of Pb (NO3) 2 is lead (II) nitrate. I was able to determine the type of link because I identified the type of linked elements. So it is an ionic bond. The cation is lead Pb2 and the anion is NO3.
The three O atoms have a total oxidation number of 6. Line 2 tells us that the sum of all oxidation numbers equals the charge on the ion. Let x = the oxidation number of N. Oxide The oxidation number of N is +5: [+ 5N2O3].
