For the procedural error, indicate if the error will affect the actual yield of copper(II) saccharinate product and if it does, will it raise or lower the actual yield:
Weighing the crystals while the crystals are still wet

it will affect the yield by raising the actual yield

Explanation:

Before crystals are weighed and the actual yield recorded, the crystals should first be dried so that water is removed and the weighed sample will only reflect the mass of the target compound. If wet crystals are weighed, the mass of water present raises the value of the actual yield above the accurate value. This is a procedural error.
