If temperature probe is measuring 1.5°C more over the entire range of experiment , then this will not cause any effect on the calculated Cmetal .
Because calculated Cmetal will be calculated by using change in temperature during the experiment.
And change in temperature = (Final - Initial)
In both Final and initial temperature , there is 1.5°C extra and thus will cancel out , giving accurate dT value.
Thus Cmetal will be unaffected.

For each of the following errors, tell whether your calculated molecular weight would be too high, too low, or unaffected. a) unawares, you inadvertently spilled some solute(so it didn't make it into the test tube) after it was weighed out. b) your thermometer is poorly calibrated and reads 0.3C lower than the actual temperature. c) while mixing the solution you spilled some over the sides of the test tube. Assume the solution was well mixed before the spill occurred.

Suppose you use a miscalibrated thermometer that reads 1.0 degree C higher than the actual temperature throughout the entire experiment. Consider how the miscalibration affects each temperature measurement, and then determine what happens to your T_f values. What would be the overall effect on your molecular weight calculations? Suppose a small amount of your solid sample is lost and does not get dissolved in the solvent. How does this affect your number of solute moles and your molality? What happens...

Q1. Part A.3. Some of the cyclohexane solvent vaporized during the temperature versus time measurement. Will this loss of cyclohexane result in its freezing point being recorded as too high, too low or unaffected? Explain. (3 pts.) Q2. Part A.3. The digital thermometer is miscalibrated by +0.15°C over its entire range. If the same thermometer is used in part B.2, will the reported moles of solute in the solution be too high, too low, unaffected. Explain. (2...

7.How would the molar mass of the unknown acid be affected (higher, lower, or no change) if the follow-ing errors occurred? Briefly explain why in each case. a.The pH meter was incorrectly calibrated to read lower than the actual pH. b.During the titration, several drops of NaOH missed the reaction beaker and fell onto the bench top. c.In Part B of the procedure the acid was dissolved in 75 mL of distilled water rather than the 50 mL called for...
