To find the mass of Y that reacted, subtract the mass of X from the total mass of XY: Mass of Y = Mass of XY - Mass of X Mass of Y = 78.9 g - 12.2 g Mass of Y = 66.7 g

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
