Write chemical equation for solid cadmium carbonate, water, and carbon dioxide

Acetic acid, hc2h3o2, dissolves and completely dissociates in water and a solvation sphere of water molecules forms around the ions. this solute-solvent interaction

What mass of carbon dioxide is produced from the complete combustion of 4.50×10−3 g of methane?

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.
