CHM 2045C Module Two Sample Exam

Module Two: Part G Temperature Conversion 8 points

State the general formula for the conversion of temperatures on scale X to temperatures on scale Y:

convert -190^oC to ^oF

convert -190^oC to K

The Rankin scale uses a Fahrenheit unit, but assumes zero to be absolute zero. If absolute zero on the Kelvin scale is zero and on Celsius scale is -273^oC, calculate absolute zero on the Fahrenheit scale, then estimate the Boiling point of water on the Rankin scale.

Bonus: Professor Taylor created his own temperature scale with the boiling point of water at

250 ^oT and the freezing point of water at 50 ^oT. What is normal body temperature ( 37 ^oC) on the Taylor Scale? Is there a temperature at with the Taylor Scale is equal to the same temperature on the Celsius Scale? Or the Fahrenheit Scale?

Module Two: Part H Density/Specific Gravity Calculations 5 points

A 25.0-mL sample of liquid bromine has a mass of 78.020 g. What is the density of bromine?

If a sugar solution weighs 4.678 grams and has a volume of 4.67 ml, calculate the density of the solution.
