What are the basic characteristics of an SN2 reaction?
Strong nucleophile, polar aprotic solvent, cannot be done on a tertiary carbon.
Given 6.0 g of sodium (Na) and 7.5 g of chlorine (Cl), how much sodium chloride could be made?
The molar mass of sodium (Na) is 22.99 g/mol. 6.0 g Na x (1 mol Na/22.99 g Na) = 0.26 mol Na. The molar mass of chlorine (Cl) is 35.45 g/mol. 7.5 g Cl x (1 mol Cl/35.45 g Cl) = 0.21 mol Cl. Because Cl and Na will be in a 1:1 ratio in NaCl, Cl is the limiting reagent. Therefore, 0.21 mol of NaCl could be generated.

How many moles of sodium chloride are there in a 65 g sample?
The molar mass of sodium chloride (NaCl) is 58.44 g/mol. Therefore, 65 g NaCl x (1 mol NaCl/58.44 g NaCl) = 1.11 mol NaCl.
