Lead(II) chromate is the inorganic compound with the formula (Pb Cr O 4).It has a vivid yellow color and is insoluble in all solvents. [citation needed]. Lead(II) chromate can be produced by treating sodium chromate with lead salts such as lead(II) nitrate or by combining lead(II) oxide with chromic acid. Hence, the formula of lead(IV) chromate is {eq}Pb(CrO_4)_2 The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. Molar mass of PbCrO4 = 323.1937 g/mol Convert grams Lead(II) Chromate to moles or moles Lead(II) Chromate to grams. This site explains how to find molar mass. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Lead(II) chromate and "white lead", or lead(II) carbonate, were the most common lead-based paint pigments. What is the formula for lead(iv) dichromate? [4], In the 1800s, the product was used to impart a bright yellow color to some types of candy. Ano ang Imahinasyong guhit na naghahati sa daigdig sa magkaibang araw?
