Answer
Explanation:
Step1: Recall mass - number formula
The mass number ($A$) of an atom is the sum of the number of protons ($p$) and neutrons ($n$), i.e., $A=p + n$.
Step2: Substitute given values
Given $p = 6$ and $n=7$, then $A=6 + 7$.
Step3: Calculate the mass number
$A = 13$.
Answer:
C. 13 amu
