In the equation, for every 1 molecule of 2-propanol there will be 1 molecule of water formed. If the molecular mass of 2-propanolol is 60g/mol, the number of molecule of 2-propanolol would be: 6.8g/ (60g/mol)= 0.1133 mol
The number of water molecule formed by the 2-propanolol would be: 1*0.1133 mol= 0.1133 mol
If the molecular mass of water is 18g/mol, the weight of the water would be:0.1133 mol* 18g/mol= 2.04 grams
