Which of the foll A. (i)

B. (i) and (iv)

C. (ii) and (iii)

D. (ii) and (iv)

(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
