Respuesta :

you divide the number of moles of NaC1 by the volume of the solution.  70.1

Answer:

The mass of 1.20 moles of sadium chloride is 70.1 grams

Explanation:

Step 1: Data given

Number of moles NaCl = 1.20 moles

Molar mass of NaCl = 58.44 g/mol

Step 2: Calculate mass of NaCl

Mass = moles * molar mass

Mass NaCl = 1.20 moles * 58.44 g/mol

Mass NaCl = 70.1 gram

The mass of 1.20 moles of sadium chloride is 70.1 grams
