Step 1
NaCl is a salt and its molar mass is calculated as:
The molar mass of NaCl = 35.5 g/mol (Cl) + 22.9 g/mol (Na) = 58.4 g/mol
--------------------------
Step 2
Information provided:
Number of moles of NaCl = 3.66 moles
--------------------------
Step 3
Number of moles = n = mass of NaCl/the molar mass of NaCl
The molar mass = 58.4 g/mol (from Step 1)
Procedure: for NaCl
n = mass/molar mass
n x molar mass = mass
3.66 moles x 58.4 g/mol = 214 g approx.
Answer: mass of NaCl = 214 g
