Answer to Question #150513 in Organic Chemistry for Maria

Question

Calculate the mass of salt (NaCl) that is expected to be made based upon the mass of NaHCO3 used. This is called the 'theoretical mass of NaCl'.

Answer 1

M(NaCl) = 23+35.5 = 58.5 g/mol

M(NaHCO₃) = 23+1+12+16*3 = 84 g/mol

As NaCl and NaHCO₃ have the same amount of Na, theoretical mass of NaCl will be:

m(NaCl, theor) = m(NaHCO₃)/M(NaHCO₃)*M(NaCl) = m(NaHCO₃)/84*58.5 = m(NaHCO₃)/1.436

Answer: m(NaHCO₃)/1.436
