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

[.AR6rider.]

Are you in like special kid math? 5.102 x 10^14

 

[Jib-Ninja]

just typed that in and got it incorrect. you are insulting my level of academics....and you got the answer wrong?????? seems legit.

oh and chemistry is now a math class? According to you it must be.

 

[Loco-Deer-Slayer]

Wooooow....woooow....just wow

1e+14 = 1 x 10^14

Don't quit your day job buddy

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

You do realize you do a shit load of math in chemistry right? I mean you must if you are in it, and doing a problem with math right now.

 

[.AR6rider.]

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.

 

[Loco-Deer-Slayer]

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.

[infedel_one]

PLUG IN THE 10^WHATEVER AS 0'S BECAUSE THATS WHAT THEY REPRESENT.

 

[jmasterp]

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

Ight i got another chem question.

Balance and complete the acid base reaction Ca(OH)2 + HCl →

I tried Ca(OH)_2 + 2HCl -->2HOH + CaCl_2

 

[skitheWest.]

came in here to post...

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?
