Question

How many atoms are in 5.00g of carbon

Question 1 options:

3.62 x 1025 atoms C


2.51 x 1023 atoms C


2.51 x 1024 molecules C


3.62x 1023 atoms C

Answer 1

Answer:

2.51 x 1023 atoms C

Explanation:

MW C = 12.011

5g x (1mol/12.011g) =0.416 mol

0.416 mol x (6.022x10^23) = 2.51 x 1023 atoms C
