B. (i) and (iv)

C. (ii) and (iii)

D. (ii) and (iv)

Answer :

(ii) and (iv) options correctly represent 360g of water.

(ii) 1 mole of water = molar mass of water = 18g


Thus, 20 moles of water = 18g x 20 = 360g


(iv) 1 mole of water = 6.022 x 1023 molecules of water = 18g of water


Thus, 1.2044×1025 molecules of water =


= 360g
