Chapter 1, Problem 56c

Determine the appropriate conversion factors for the following: c. mi to km

Verified step by step guidance
1
Identify the relationship between miles and kilometers. The conversion factor is 1 mile = 1.60934 kilometers.
Set up the conversion factor as a fraction. You can write it as \( \frac{1.60934 \text{ km}}{1 \text{ mi}} \) or \( \frac{1 \text{ mi}}{1.60934 \text{ km}} \), depending on the direction of conversion.
If converting from miles to kilometers, use the conversion factor \( \frac{1.60934 \text{ km}}{1 \text{ mi}} \).
Multiply the number of miles by the conversion factor to convert to kilometers.
Ensure that the units cancel appropriately, leaving you with the desired unit of kilometers.

Dimensional Analysis

Dimensional analysis is a mathematical technique used to convert units by canceling out dimensions. It involves multiplying the quantity by conversion factors in such a way that the unwanted units cancel out, leaving the desired units. This method ensures that the final answer is in the correct unit and is a fundamental skill in chemistry for solving problems involving different units.
