Final answer:

The distance between the centers of the two oxygen atoms in an oxygen molecule, given as 1.21× 10⁻⁸ cm, is equivalent to 4.76× 10⁻⁻ in when converted from centimeters to inches. Option a is correct.

Step-by-step explanation:

To convert the distance between the centers of the two oxygen atoms in an oxygen molecule from centimeters to inches, we use the conversion factor that 1 inch equals 2.54 centimeters. Therefore, to find the distance in inches, you divide the distance in centimeters by 2.54:

1.21 × 10⁻⁸ cm ÷ 2.54 cm/in = 4.76× 10⁻· in.

So, the correct distance in inches is 4.76× 10⁻· in, which corresponds to option (a).
