Match the measurements to the correct number of significant figures.?

Answer 1

To match measurements to the correct number of significant figures, first identify the significant figures in each measurement. For example, the measurement 0.00456 has three significant figures, while 100 has one significant figure unless specified otherwise (like 100. indicating three). It's important to consider leading zeros, trailing zeros, and whether the measurement is in scientific notation, as these factors affect the count of significant figures. Always ensure to express the numbers accurately based on their precision.

Answer 2

To match measurements to the correct number of significant figures, you must consider the precision of each value. For example, a measurement like 0.00456 has three significant figures (4, 5, and 6), while 1200 has two significant figures if no decimal is present. In contrast, 1200.0 would have five significant figures due to the decimal indicating that the zeros are significant. Always look for non-zero digits, zeros between significant figures, and trailing zeros with a decimal point to determine the total count.
