The student recorded the mass of the cup + sample incorrectly and started with 2.20 g of hydrated compound but used 2.00 g in the calculations. Explain how this error will affect the calculation for the number of moles of water in the hydrate? Will the final answer be artificially high or low? How do you know?

Answer:

low

Explanation:

We were informed in the question that the student had incorrectly recorded the mass of cup + sample as 2.20 g but inadvertently used 2.00 g in the calculations.

This error will cause a slight decrease in the mass of water and ultimately decrease the number of moles of water in the hydrate.

What i am saying is that the number of moles of water obtained in the calculation will be artificially low.
