How to Calculate Molecular Weight: 6 Steps (with …

WebSolution: Since sodium carbonate contains two atoms of sodium, one atom of carbon and three atoms of oxygen. The molecular weight would be. Na : 2 x 23.0 = 46. C : 1 x 12.0 = 12. O : 3 x 16 = 48. When we add up the total values i.e, 46 + 12 + 48 = 106. Therefore, the molar mass of Na 2 CO 3 is 106 g/mol. WebThe equation to convert moles to atoms is as follows: B moles x 6.022×10^23 atoms/ 1 mole = C atoms In other words, you take the number of moles of a substance (B) and then multiply it by Avogadro’s number (divided by one mole). An example calculation: How many atoms are there in six moles of iron?: 6 moles x 6.022×10^23 atoms/ 1 mole = C atoms Web2 jun. 2024 · You use the periodic table to look up the mass of each atom (H is 1.01 and O is 16.00). Forming a water molecule gives you a mass of: 1.01 + 1.01 + 16.00 = 18.02 grams per mole of water and you solve with: mass of 1 molecule = mass of one mole of molecules / … hoimonty mazumder
