Verified step by step guidance

Understand that 1 angstrom (Å) is equal to 1 x 10^-10 meters. This is a fundamental conversion factor in chemistry for converting lengths from angstroms to meters.

Start with the given value of 7000 Å. To convert this to meters, you will multiply by the conversion factor (1 Å = 1 x 10^-10 meters).

Set up the conversion equation: 7000 Å * (1 x 10^-10 meters/1 Å). Notice that the unit 'angstroms' will cancel out, leaving you with meters.

Perform the multiplication: 7000 * 1 x 10^-10. This involves multiplying the numerical part (7000) by the power of ten (10^-10).

Express the result in scientific notation. Remember that scientific notation involves expressing a number as a product of a number between 1 and 10 and a power of ten. Adjust the decimal point in 7000 to fit this format.
