Question

A sample of carbon-12 has a mass of 6.00 g. How many atoms of carbon-12 are in the sample?

Answer 1

Answer:

A    

Explanation:

Answer 2

Carbon molar mass=12
carbon mass in the above question =6
mole=number of atoms/6.02x10²³
6/12= number of atoms/6.02x10²³
number of atoms=1/2 x6.02x10²³
number of atoms= 6.02 x10²³/2
number of atoms=3.01x10²³
