Dimensional Analysis and Unit Conversion Quiz

What is the primary goal when using dimensional analysis for unit conversion?

• To use as few conversion factors as possible

• To cancel out the starting units and achieve the desired ending units

• To ensure the starting and ending units are the same

• To memorize all conversion factors

In the example of converting 24.5 g/cm3 to kg/L, why is it important to arrange the conversion factors correctly?

• To make the calculation faster

• To reduce the number of conversion factors needed

• To ensure the units cancel out properly

• To avoid using a calculator

What is the conversion factor for grams to kilograms?

• 1 g = 1 kg

• 1000 g = 1 kg

• 1 g = 1000 kg

• 100 g = 1 kg

When calculating the volume of CO2 exhaled per month, why is it important to consider significant figures?

• To avoid using scientific notation

• To ensure the answer is as precise as possible

• To make the calculation easier

• To reduce the number of conversion factors

How is the final answer expressed in the CO2 production example?

• As a fraction

• In scientific notation

• In decimal form

• As a whole number
