Essentially, stoichiometry is often just a game of proportions. So if everything is in kilograms, you can divide through by 1000 to get grams. When you get the final result in grams, multiply by 1000 to get the final result in kg.
You can do it the long way but you will end up working with bulky numbers which will slow down your calculation. Either way, you'll get the same answer. |
