how many grams of carbon are in 12 x 1023 atoms of carbon?

Sagot :

Answer:

23.9 grams carbon

Explanation:

One mole of carbon is 6.023 x 10^23 atoms of C.

If we calculate moles, we can use the molar mass of carbon (12 g/mole) to determine mass of 12x10^23 atoms of C.

(12x10^23 atoms of C)/(6.023 x 10^23 atoms of C/mole C)

moles C = 1.992 moles C

(1.992 moles C)*(12 g/mole C) = 23.9 grams carbon
