The distance between carbon atoms in ethylene is 134 picometers. Which of the following expresses that distance in meters? A)1.34 × 10 ⁻¹³ m B)1.34 × 10 ⁻12 m C)1.34 × 10 ⁻¹⁰ m D)1.34 × 10 ⁻⁷ m E)1.34 × 10 ⁻⁶ m

Question

Quizplus · Accepted Answer

To convert picometers to meters, we need to move the decimal point 12 places to the left (since there are 10^12 picometers in a meter).

Thus, the distance between carbon atoms in ethylene is:

134 pm = 134 x 10^-12 m = 1.34 x 10^-10 m

The only answer choice that matches this expression is C:

1.34 x 10^-10 m = 1.34 x 10^-1 * 10^-9 m = 1.34 x 10^-1 nm

Therefore, the correct answer is:

Answer: C

The Distance Between Carbon Atoms in Ethylene Is 134 Picometers
