I need help with my chem homework.

Earths surface has an area of 197 million square miles...convert to the following:

square meters

Round to the right amount of significant digits if you would please :) Thanks, much appreciated.

Use Wolfram Alpha. This website was incredibly helpful to me in Chemistry last year.

I have no idea what number of significant digits you are supposed to round to, I just didn't feel like typing out all the decimal points, which is why I rounded. I've already helped you out enough, you can at least figure something out yourself.

Here's how you do it without using a google converter

197e6 miles^2 * (1609.34 meters/ 1 mile)^2

That will get you meters and just look up the prefixes for the other conversions.

8 you're welcome. But on the real, just use factor label. It's simple chemistry.

This should be right but make sure you check the charges when you switch them because that could fuck you up, i dont have a periodic table in front of me and to lazy to look up. Also OH is a polyatomic remember.

Did you know that the same internet you're posting on right now is filled with all kinds of crazy next level tools like conversion calculators?

It's wild I know?


You can click on google, and type that in and have a choice of different types of conversion calculators to help you, many of them even have multiple choices of conversion right there.

it's so wild.


The internet is amazing right?
