Question

Will someone help me with this question? “A hydrogen atom has a diameter of about 10.2 nm. Express this diameter in meters. Answer in units of m.”

Answer 1

1.02×10⁻⁸m

Step-by-step explanation:

1 nanometer (nm) = 0.000000001 meters (m) or 1×10⁻⁹ m

So if you multiply the given 10.2nm by 1×10⁻⁹m, you'll get your value in meters.

(10.2nm)•(1×10⁻⁹m/1nm)= 1.02×10⁻⁸m or 0.0000000102 meters
