Question

Calculate the mass of sodium chloride produced when 5.50 moles of sodium reacts in excess chlorine gas

Answer 1

The mass of NaCl produced is calculated  as below

write the reacting equation

that is  2 Na + Cl2 =2 NaCl

by use of mole ratio between Na :NaCl which is 2 :2 t he moles of NaCl is also = 5.50 moles

mass  of NaCl= moles x molar mass

=5.50 moles  x58.5 g/mol = 321.75 grams
