Question

9. How many grams are in 3.01 x 1023 atoms of carbon?

Answer 1

Avogadro's Number: N = 6.022 x 10^23 particles per mole. First, we want to find how many moles make up 3.01 x 10^23 atoms.

Answer 2

# of moles of C = 3.01e23 atoms/ 6.022e23 atoms/mol

Answer 3

Next we need the molar mass of carbon, which can be simply found on the periodic table. For Carbon, 1 mole equals 12.01g.

Answer 4

So, total mass = # of moles * 12.01g/mol

Answer 5

would it be 6.005?

Answer 6

Yes, 6.005 grams.

Answer 7

Thanks!
