How would each of the following errors have affected the value of the molar mass? (For each, write "too large", "too small", or "no effect"). a) The FP of cyclohexane was read too high.______ b) The FP of the solution was read too high._______ c) A student used 10 mL of cyclohexane and converted it directly to 10 g without weighing it.____ d) A student spilled some of the unknown after weighing it, so that not all of the weighted...

1. A student performed a freezing point determination and calculated the molar mass of an unknown like you did in this experiment. The only difference in procedure was that when determining the freezing point of the unknown-naphthalene mixture, they started with a clean empty test tube. If the following errors occurred, how would each affect the calculated molar mass of the solute (too high, too low, or no change)? Explain your answers. a. The thermometer used actually read 2.0 celcius...

1A) How will the calculated Ksp value of Ca(OH)2 be affected if the original Ca(OH)2 solution is not saturated? Explain? B) Does adding distilled water to the titrating flask in order to wash the sides of the flask and the buret tip affect the computed Ksp of Ca(OH)2? Explain? C) How might tap water instead of distilled water affect the calculated Ksp of Ca(OH)2? Explain? D) The temperature of the solution was 21.1 degrees Celcius. Is the molar solubility of...

Explain what effect the following scenarios would have on the calculated specific heat (i.e. would it be calculated artificially high, low, or have no effect). Your explanation should address what variable(s) would be affected by the scenario and how that affects the calculation of specific heat.(1.5pt each) A student accidently dropped the piece of metal on the countertop during the process of transferring it from the boiling water bath to the calorimeter, but was quickly picked up and put into...

2. How would the calculated value of the ratio (Equation 4) be affected (too high or too low) if you incorrectly read the temperature of the boiling water and record a temperature that is: a. too high? Explain your answer. b. too low? Explain your answer. 171 De SUILLUS # 3 Vernier LabQuest kit # Symbol T T Meaning Boiling water temperature -- data taken Ice water temperature - data taken...

how would the calculated molar mass change if the following experimental problems were encountered? Explain the reasons for your answer. a. the unknown was impure and only part of the unknown dissolved in the Lauric acid. b. your unknown contained a substance that produced two ions per molecule of unknown when dissolved in the Lauric acid. (experiment on Lauric acid for freezing point depression)

How would the calculated molar mass change (increase,decrease, no change) if the following experimental problems were encountered? Explain the reason(s) for your answer. a) The unknown was impure and only part of the unknown dissolved in the lauric acid. b) Your unknown contained a substance which produced two ions per molecule of unknown when dissolved in the lauric acid. c) The unknown was insoluble in lauric acid. d) A very small amount of lauric acid was spilled after weighing, but...

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.
Molecular Weight of a Volatile Liquid In this experiment, an amount of liquid more than sufficient to fill the flask when vaporized is placed in a flask of measured volume and mass. The flask is then heated in a boiling...
