molar mass for iron iii carbonate

The Mole

The mole is thus the link between the micro world of atoms and molecules and the macro world of grams and litres the which we can easily measure by mass or volume The masses for a mole of each element are given on the periodic table as the atomic weight So if have 12 g of #C# I know fairly precisely how many atoms of carbon I have

How do you calculate the maximum mass that can be produced

Moles of Iron (mass divided by Mr) Now look at the molar ratio (the number in front of the compounds/elements in the equation) So for every 2 moles of iron you use you make 2 moles of iron chloride so the ratio is 1 1 This means the number of moles of iron chloride = the moles of iron Then just work out the mass (moles x Mr of iron chloride)
