Question

I have a few questions.

1. Suppose the thermometer is miscalibrated to read 0.3 oChigher than actual. Does this error in calibration result in themolar mass of the vapor in the flask being reported as too high ortoo low or as unaffected? Explain.

2. If the volume of the flask is assumed to be 125mL instead ofthe measured volume, would the calculated molar mass of the unknownliquid be too high or too low or as unaffected by this experimentalerror? Explain.

3. The pressure reading from the barometer is recorded higherthan it actually is. How does this affect the reported molar massof the liquid: too high, too low, or unaffected? Exlplain.
