If 4.61 grams of Pbl2 was isolated from the reaction of Pb(NO3)2 and Nal, what will be the calculated amount of Nal that reacted with Pbl2? Molar Mass: 461.0089. The nitrate ion is a radical with an overall charge. Solubility Product of PbI2. picture. If the correct molar mass had been used, 12.1 grams of PbI2 would have been produced.]. Using scientific notation, state the mass in amu of ten million such atoms. by Raymond Esterly. Molar mass PbI2 = 461g/mol . The reason is that the molar mass of the substance affects the conversion. pbbr2 molar mass, ∴ moles of Ni = mass/atomic wt = 0.587/58.71 = 1.00 x 10-2 mol and moles of electrons required = 2 x 1.00 x 10 -2 = 2.00 x 10 -2 mol. Finally, use the molar mass of PbI2 to find the mass of PbI2. common chemical compounds. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. A common request on this site is to convert grams to moles. Chemistry.
