Ask Question + 100. Molare Masse of K3PO4(s) is 212,2663 g/mol. Formula: K3PO4. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. Kaliumphosphat Strukturformel 3 K+ Allgemeines Name Kaliumphosphat Andere Namen Trikaliumphosphat Summenformel K3PO4 CAS-Nummer 7778-53-2 Eigenschaften Molare Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. 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. How do you think about the answers? For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. a) K3PO4 (aq)+ 3 AgNO3 (aq)>> Ag3PO4 (s)+ 3 KNO3 (aq) b) molar mass K3PO4 = 212 g/mol. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. a = 1.123772 nm, b = 0.810461 nm, c = 0.592271 nm.
