**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^{o}C to ^{o}F

convert -190^{o}C 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** ^{o}**C, 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 ^{o}T and the freezing point of water at 50 ^{o}T. What is normal body temperature ( 37 ^{o}C) 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.
