Because 0.12 molecule of water can't exist.
Molecule are always exist in simple whole number ratio. Like 1,23,4 etc.
Answer you get is 5.12 which is due to experimental data error.
Add Answer to:

CHM 010 On-Line Lab, Formula of a Hydrate PURPOSE: To determine the formula of Cuso..x H20. In other words, to determine the value of "X". PROCEDURE: When copper(II) sulfate x hydrate, a blue crystalline solid containing embedded water molecules (called a hydrate), is heated in air, it loses the water molecules and the blue solid is transformed to a white anhydrous (no water) crystal known as anhydrous copper(II) sulfate. The "x" represents a whole number of water molecules attached to...
