Answer:
The molecular weight of NaCl is 58.5 – meaning 1 mole of NaCl is 58.5g. As NaCl is composed of two atoms, Na and Cl – there is 1 mole of sodium ions (which weighs 23g) and 1 mole of chloride ions (which weighs 35.5g).
Explanation:
sodium chloride (NaCl) has one atom of sodium (Na) and one atom of chlorine (Cl). The atomic weight of sodium is 22.99 g/mol and chlorine is 35.45 g/mol. Therefore, the formula weight of NaCl is 58.44 g/mol (22.99 g/mol + 35.45 g/mol).
