In the United States, the emissions limit for carbon monoxide in motorcycle engine exhaust is 12.0 g of carbon monoxide per kilometer driven. What is this limit expressed in mg per mile with the correct number of significant figures?
Guida verificata passo dopo passo1
Convert the emissions limit from grams to milligrams. Since 1 gram is equal to 1000 milligrams, multiply 12.0 g by 1000 to convert to mg.
Convert kilometers to miles. Use the conversion factor: 1 kilometer is approximately 0.621371 miles.
Divide the emissions limit in milligrams by the conversion factor to express the limit in mg per mile.
Ensure the final answer has the correct number of significant figures. The original value, 12.0 g, has three significant figures, so the final result should also have three significant figures.
Compile the result, ensuring all units are correctly labeled as mg per mile.

Conversion Factors
Significant Figures
Significant figures are the digits in a number that contribute to its precision. When performing calculations, especially conversions, it is essential to maintain the correct number of significant figures based on the precision of the given data. In this case, the emissions limit of 12.0 g/km has three significant figures, which will guide how we express the final answer.
