Dave. 8 years ago. you have to add the molar mass of each atom together to get the total molar mass of the compound. H-1 2 O molar mass: 2 × 16.00 g = 32.00 g: 2 H molar mass: 2 × 1.01 g = 2.02 g: Total: 171.35 g: Because molar mass is defined as the mass for 1 mol of a substance, we can refer to molar mass as grams per mole (g/mol). The division sign (/) implies per, and 1 is implied in the denominator STEP 3: Calculate any molar masses (formula weights) needed and fill in the numbers using the balanced equation to find the molar ratios. 0.043 g O 16.00 g O 1 mole O 4 mole O 1 mole Ca C 2 O 4 1 mole Ca C 2 O 4 1 mole Ca Cl 2 1 mole Ca Cl 2 2 mole Cl 1 mole Cl 35.45 g Cl = 0.048 g Cl molar mass molar ratio molar ratio molar ratio molar mass Since N has a molar mass of 14 g/mol and O has a molar mass of 16 g/mol, the formula N 2 O would produce the correct molar mass.. Step 3: Think about your result. The R value that corresponds to a pressure in atm was chosen for this problem. The calculated molar mass gives a reasonable formula for dinitrogen monoxide

Molar mass of Sodium = Relative atomic mass of Na = 23 g mol-1. Molar mass of Water = Relative molecular mass of H 2 O = 1 + 1 + 16 = 18 g mol-1. Molar mass of Sodium Chloride = Relative formula mass of NaCl = 23 + 35.5 = 58.5 g mol-1 . Note: Sodium is a metal made up of only Na atoms;. Molar Mass of Fe 2O3 = 2 (55.85 g/mole) + 3 (16.0 g/mole) = 159.7 g Fe 2O3/mole Stoichiometry Chapter 4 x 4 Fe + 3 O 2 2 Fe 2O3. 6 Stoichiometry The steel industry relies on the reaction between iron(III) oxide and carbon to produce iron and CO 2 Use chemical symbols to compose the molecular formula: {{Chem molar mass|H=2|O=1}} (for H 2 O) → ۱۸٫۰۲ g·mol −1 |round= by default the calculated number is rounded to 2 decimals. |round=no will show all decimals: {{Chem molar mass|Be=1|round=no}} → 9.0121831 g·mol −1 |round=a number will round to that number of decimal
