//INPUT
W = 100; //Weight of solution in grams(Basis of calculation)
w1 = 40; //Weight of sodium carbonate present in solution in grams
MW = [106,18.02]; //Molecular weight of sodium carbonate and water respectively in g/g-mole
//CALCULATION
n1 = w1/MW(1); //To find the no of moles of sodium carbonate in g mole
n2 = (W-w1)/MW(2); //To find the no of moles of water in g mole
N = n1+n2; //Calculation of total no of moles in g mole
x1 = n1*100/N; //Mole % of sodium carbonate
x2 = n2*100/N; //Mole % of water
//OUTPUT
mprintf('\n mole percent of Na2CO3 = %4.2f',x1);
mprintf('\n mole percent of H2O = %3.1f',x2);
