Answer :

(a) The chemical formula of caustic potash is KOH.

Molecular mass of Caustic potash (KOH) = The molar mass of K + the molar mass of O + molar mass of H


= 39 + 16 + 1 = 56g/mole


(b) The chemical formula of baking powder is NaHCO3.


Molecular mass of baking powder (NaHCO3) = 23 + 1 + 12 + 3 X 16


= 84g/mole


(c) The chemical formula of Lime stone is CaCO3.


= 40 + 12 + 3X16


= 100g/mole


(d) The chemical formula of Caustic soda is NaOH.


Molecular mass of Caustic soda (NaOH) = 23+ 16+1


= 40g/mole


(e) The chemical formula of Ethanol is C2H5OH.


Molecular mass of Ethanol (C2H5OH) = 2 X 12 + 5 X 1 + 16 + 1


= 46g/mole


(f) The chemical formula of Common salt is NaCl.


Molecular mass of Common salt (NaCl) = 23 + 35.5 = 58.5g/mole
