Determine what effect the following errors would have on the value for the mass percent water for your hydrate.

a. The hydrate was not heated long enough to drive off all the water. 1) This error will increase/decreaselleave unchanged the mass in grams for "mass crucible and dehydrated compound after heating". 2) The error for "mass crucible and dehydrated compound after heating" that you determined above will result in an increase/decrease/leave unchanged for your calculation of the mass of the dehydrated compound. 3) This will increase/decrease/leave unchanged the value for the "mass of water lost during heating" in your calculations. 4) This error will cause your ratio of water to Cu in your hydrate to be higherllower/unchanged than it actually is, meaning the number for the Cu is 1 , but the number for the water is high/low/unchanged
