As a results of a manufacturing error, a thermometer was miscalibrated by +2 degrees celsius. If the thermometer was used in this experiment, would it cause the determined molar mass to be higher, lower or the same as if would be had a properly calibrated thermometer has been used? Explain.

At 22.0 degrees Celsius an "empty" 30-ml syringe had a volume of 5.0 ml. After a liquid is introduced and the temperature is raised to 32.0 degrees Celsius, the volume becomes 10.2 ml. The barometer pressure is 745.8 mmHg, 1. what was the pressure of the air inside the syringe when the syringe was "empty"? 2. What is the pressure of the air inside the syringe after the liquid has been introduced and the temperature raised to 32.0 degrees Celsius?...

Typically, an individual's normal body temperature is about 37 degrees Celsius. When a body enters hypothermia, its temperature dramatically decreases below 35 degrees Celsius. In this situation, the body’s organs will slowly start to degrade in metabolic function and cardiac output and heart rate will become depressed. Likewise, in consequences, a fever, a body temperature between 38 to 42 degrees Celsius, may cause many systemic effects such as cognitive dysfunction and liver failure. In either case, it becomes equally important...

A special mercury thermometer which reads in Celsius has a distance of 8.3 mm between each degree marking (for example: from 2°C to 3° is 8.3 mm). If the temperature in the morning was 62 °F and the temperature later on around lunch time was 92°F, how many mm did the level of the liquid travel up the thermometer?

answer all parts: 2. You measured the volume of the CO2 by filling your flask with water and tightly inserting the stopper. a. Why was it necessary to tightly stop the water-filled flask and then remove the stopper before you emptied the water into a graduated cylinder for measurement? b. Would your calculated molar volume of CO2 (Vm) have been higher or lower if you had forgotten to stopper the flask before measuring the volume of the flask (V1)? Briefly...

DISCUSSION QUESTIONS 1. If the liquid did not completely vaporize in the experiment, would the ap- parent molecular weight be larger, smaller, or unchanged compared to that determined if the experiment had been properly performed?
