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.

How do you calculate what mass of magnesium chloride is formed when 54.75g of HCl is reacted with sufficient magnesium?
By starting with a balanced equation. Mg + 2HCl -> MgCl2 + H2 when they say sufficient magnesium they imply that magnesium is in excess and HCl limits and drives the reaction, or that both are equal in molarity/mass 54.75 g HCl (1 mole HCl/36.458 g)(1 mole MgCl2/2 mole HCl)(95.21 g/1 mole MgCl2) = 71.49 grams magnesium chloride produced -----------------------------------------------------------

What is the molarity of a solution made with 128 grams of magnesium chloride dissolved in one liter of water?
Molarity= moles/Liters To change grams to moles you divide by the mole weight which is listed on the periodic table. Mol= grams/mol weight The Mole weight of Magnesium Chloride is 59.8 grams/mol Mol=128g/59.8 Mol=2.14 Now, you put the number of moles and Liters into the equation Molarity=2.14 mol/1L Molarity=2.14 So, the molarity is 2.14 M
