Four grams of caustic soda contains: (a) 6.02 x 10 23 atoms of it (b) 4 g atom of sodium (c) 6.02 x 10 22 molecules (d) 4 moles of NaOH

6.02 × 10 22 molecule Reason Molar mass of NaOH = Na + O + H = 23 + 16 + 1 = 40 g 40 g of NaOH contains 6.022 × 10 23 molecules 4 g of NaOH contains = x 4 = 6.02 × 10 22 molecules
