A) 11 g/mol
B) 28 g/mol
C) 34 g/mol
D) 40 g/mol
E) 58 g/mol

Question

Quizplus · Accepted Answer

NaCl is composed of one sodium (Na) atom and one chlorine (Cl) atom. To calculate the molecular weight, we add the atomic weights of both atoms together:

23 g/mol (Na) + 35 g/mol (Cl) = 58 g/mol (NaCl)

Therefore, the correct answer is E.
