The diameter of a watermolecule is 0.000000000275 m. How can this number best be expressed in scientific notation

2.75x10⁻¹⁰m

Explanation:

By scientific notation, we have to express 0.000000000275 m in powers.

This can be done by counting the number of zeros after the decimal and the number after 0 which is 2.

from 2 to the decimal point, we have 10 characters

so we express it scientifically as,

= 2.75x10⁻¹⁰m

for easy understanding. i have added an attachment to help you out on how to do this.

attach the statements so i can answer : )
