Or … WebQ-11: Calculate the molecular mass of magnesite to three significant figures using the table of atomic weights. Answer: The chemical formula of magnesite is MgCO 3. Atomic weight of Mg = 24.305 u. Atomic weight of C = 12.011 u. Atomic weight of O = 15.999 u.
WebThe molar mass of the gas can then be calculated by dividing the molecular weight of the gas by the number of molecules in one mole of the gas, which is known as Avogadro's number (6.022 x 10^23). Finally, the molar mass of a gas can also be determined by measuring the gas's viscosity, which is a measure of the gas's resistance to flow. The ... WebCalculating amounts in moles.
