Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Question

For example, dimensional analysis could be used to determine the number of nickels in 3432.35 dollars.
34R5 dellar
• To begin, write down the starting value, 3432.35 dollars. This can also be written as a fraction:
• Next, convert dollars to cents. This conversion involves a simple conversion factor: Note that the "dollar" unit should appear on the bottom of this conversion
factor, since "dollars" appears on the top of the starting value.
• Finally, convert cents to nickels. This conversion also involves a simple conversion factor. This time "cents" should be on the bottom of the conversion factor,
I dellar
S centa
since it was on top of the previous conversion factor.
• Combining these expressions gives us
100 cents
1 dollar
• Finally, cancel units. Since dollars are divided by dollars, and cents are divided by cents, both of these units can be canceled. Multiplying through gives the final result:
100 cents
1 dolhar
1 nickel
5 cents
3432.15 dollars
3432.35 dollars
1 nickel
68, 647 nickels
• To complete the calulation, multiply everything in the numerator and divide by everything in the denominator (or top and bottom, respectively).
