The formula of magnesium carbonate is MgCO3. It therefore has one atom each of magnesium and carbon and 3 atoms of oxygen. The gram molecular weight is therefore
24.305 + 12.011 + 3(15.999) = 84.313. This answer to the problem is twice this value, 168.626 grams, if the number "two" is considered to be exact.
For this you need the atomic (molecular) mass of MgCl2. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel. MgCl2= 95.3 grams
2.00 moles MgCl2 × (95.3 grams) = 190.6 grams MgCl2
The molar mass of magnesium chloride (MgCl2) is 95.211 g/mol. Therefore, 2.0 moles of MgCl2 would be 190.422 grams.
