Question

What is the formula mass of sodium chloride (in units of g/mol)? Your answer should have the appropriate number of significant figures (use two decimal places in atomic masses). Only give the numeric value of your answer. Don't include the units.

Answer 1

The formula mass of sodium chloride (NaCl) is 58.44 amu.

Step-by-step explanation:

The formula mass of sodium chloride (NaCl) is 58.44 amu. The formula mass is the sum of the atomic masses of one sodium atom and one chlorine atom. The atomic mass of sodium (Na) is 22.99 amu and the atomic mass of chlorine (Cl) is 35.45 amu. Adding these together gives us a total of 58.44 amu for the formula mass of sodium chloride.

The formula mass of sodium chloride, commonly known as table salt, is the sum of the atomic masses of sodium (Na) and chlorine (Cl). The atomic mass of sodium is 22.99 amu, and the atomic mass of chlorine is 35.45 amu. Adding these two values together gives the formula mass of sodium chloride:

22.99 amu + 35.45 amu = 58.44 amu.

Therefore, when converting the units to grams per mole, which is the molar mass, this value remains the same. The molar mass of sodium chloride (NaCl) is 58.44 g/mol.
