Verified step by step guidance

1. Understand that scientific notation expresses a number as a product of a number between 1 and 10 and a power of 10.
2. Identify the original number: 702.0 g.
3. Move the decimal point in 702.0 to create a number between 1 and 10. For 702.0, moving the decimal two places to the left gives 7.02.
4. Count how many places the decimal was moved; this number becomes the exponent of 10. Since the decimal moved 2 places left, the exponent is 2.
5. Write the number in scientific notation as \$7.02 \times 10^{2}$ g, and adjust significant figures if necessary to match the original precision.
