Can you explain?
I'm lost

I'm not sure where you're going wrong. You're right to perform ((12.04*10^23)/63360)/25000.

What do you get as an answer to this? It should be somewhere near 10^13,

I think my problem is the fact that I do not multiply the 10 to the 23 to 12.04... my answer was completely off. It was .0328535*10 to the 23...
Totally wrong I think..
I don't understand the 10th power at all.. super confusing

It's scientific notation, you can write 10^23, or you can write 100000000000000000000000 (23 zeros). It's just a more compact way of writing bigger numbers.

If you are using a calculator, it will have an Exp or E button. If you hit 12.04 [Exp] 23, then it should put the number in correctly. You should talk to your teacher about this. Learning about moles before you know about scientific notation is harsh!

No.
I know about scientific notation, and all that jazz.
But I didn't understand when you put 10(23-5-5)...
Why did you subtract 5?
And my calculator is very odd.
It doesn't have any "symbols" pertaining to EXP or E..

Are you familiar with the "log" button..
I came up with the answer 1.035050704*10 to the -3

because 10^23/10^5 = 10^23-5 = 10^18

You can also just enter 12.04*10^23. You should have ^ or or some kind of similar button.

You don't want to use the log button, that's something a little different.

Okay.
I used one that has an "x" and it has like a blank next to it.
Would that be the right one?
The answer I received on the calculator with the "x" button was 7.151698532*10 to the 24

What model is your calculator? :)

It's a casio fx-115 ES

it has a x10^x button at the bottom, try using that.

just hit 12.04 [x10^x] 23

Okay.. I got 1.204*10 to the 24th

Yes, now divide by 63360, then again by 25000

Okay I got 7.601010101*10 to the 14th

that sounds right to me, it's close to 10^13 :)

Is that the final answer?
Or is it incorrect?

Okay.
Thank you!

I'm very grateful

Could you help me on this question?


The distance form Earth to the Sun is approximately 93,000,000 miles. Calculate how many times your paper clip chain could make it to the sun and back.


Would I start this problem by finding out how many inches goes into 93,000,000 miles?

Well, think about what you did in the last question!
