That looks correct. Just remember to round your answer to 3 sig fig. The question is a bit weird tho, avogadro is used to calculate the number of particles, moles * avogadro's constant, so I'm not 100% sure

That's what I thought, because it says to calculate the mass? anyway thank you!

When you change it to 6.02x10-1....watch out...you may get flustered during the exam so try to cut out any unnecessary steps :smile:

How is that an unnecessary step ?

It's just an extra line when all you have to do is type it into the calculator.

The mass of one atom of C^12 is 1.99x10^-23. Use this to calculate a value for avagadros constant.

This question is hard:frown:
I'm no where near the answer please help

You know that an Avogadro number of carbon atoms have a mass of 12.000000 g

Divide this by the mass of 1 atom and you have the number of atoms in Avogadro's number ...
