In the last one.the first thing I did was convert inches to miles.

So would I take 1.204*10 to the 24/93,000,000/63360?

Or because the question is asking for me to calculate the distance there and back.would I take 93million times 2?

Or am I overthinking?

You do need to multiply it by 2, but 63360 is your conversion from inches to miles.

So 1.204*10 to the 24 is the length of your chain in inches
1.204*10 to the 24/63360 is the length of your chain in miles and
1.204*10 to the 24/63360/25000 is the number of times the chain goes aroudn the earth.

This should be very easy to alter for your current question.

okay. So the equation would look like this.

1.204/63360/186000000 would be the equation?

yeah but don't forget your 10^24

Okay.
So the answer I got was 1.021641143*10 to the 11th

Sounds about right.

I think the point your teacher is trying to get across is htat a mole is a large number :)

Thanks a bunch..
