The molar mass and molecular weight of Cr2(CO3)3 is 284.019.Now, to calculate the molar mass of CO3, you just have to add the molar mass of all the individual atoms that are present in CO3. You can see that in CO3, there is 1 Carbon atom and 3 Oxygen atoms. So, Molar mass of CO3 = Molar mass of 1 Carbon (C) atom + Molar mass of 3 Oxygen (O) atoms. = 12.011 + (15.999) 3 = 12.o11 + 47.997 = 60.008 g/molComputing molar mass step by step. First, compute the number of each atom in PbCO 3: Pb: 1, C: 1, O: 3. Then, lookup atomic weights for each element in periodic table: Pb: 207.2, C: 12.0107, O: 15.9994. Now, compute the sum of products of number of atoms to the atomic weight: Molar mass (PbCO 3) = ∑ Count i * Weight i =.Calculate the molar mass of (CO2)3 in grams per mole or search for a chemical formula or substance.
