Question 1

Carbon has two naturally occurring isotopes, carbon-12 and carbon-13. The more common isotope of carbon is carbon-12 with an abundance of 98.93% while carbon-13 has an atomic mass of 13.00335 u. Calculate the atomic mass of carbon-12 if the atomic mass of carbon is 12.0107 u.
◦ 12.8 u
◦ 12.4 u
◦ 12.0 u
◦ 13.1 u
◦ 13.0 u

Question 2
