Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. Hope this is helpful to you. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. just find the number of moles of KCL and then using the molar ratio which is 2 is to 1 find the number of moles of PbCl2 and multiply it into your molar mass. Answer to: According to the following reaction, what mass of PbCl2 can form from 235 mL of 0.110 M KCl solution? 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. Solubility in water, hydrazine, glycerol, pyridine, sulfur dioxide, ethanol, . For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Both have the same number of ions. A chemist adds 10.00 g of PbCl2 to 50 ml of water at 25°C and finds that only 0.22 g of the solid goes into solution. Both are made up of 6.02 x 10^23 molecules. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Convert grams Lead(II) Chloride to moles  or  moles Lead(II) Chloride to grams, Molecular weight calculation: 0 0. To complete this calculation, you have to know what substance you are trying to convert. Compound: Moles: Weight, g: PbCl2: Elemental composition of PbCl2. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. Both have the same molar mass. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. The reason is that the molar mass of the substance affects the conversion. Calculate the molecular weight 101.87g is the molar mass of PbCl2 Cross multiply and cancel out the same units. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. molarity = moles PbCl2/L of solution = (0.06767 mol)/(0.2000 L) = 0.3384 mol/L.
