Question

I need to convert 234 terameters to nanometers using Dimensional Analysis. I know the answer is 2.34 x
`10^(23)`. How do I get there?

Answer 1

Step-by-step explanation:

First, convert terameters to meters.

234 Tm × (10¹² m / Tm) = 234×10¹² m

Now convert meters to nanometers.

234×10¹² m × (10⁹ nm / m) = 234×10²¹ nm

In scientific notation, that's 2.34×10²³ nm.
