(iv) 1204410 molecules of water

(a) (i)
(b) () and (iv)
(c)(ii) and (iii)
(d) (ii) and (iv)

Answer 1

Answer:

)(ii) and (iii)

Explanation:

(ii) 20 moles of water

(iii) 6.022 x 10 molecules of water

Answer 2

Answer:

=> The molar mass of water is 18 g/mol.

=> 360 g of water corresponds to

360/18=20mol.

=> It is also equal to 20mol×6.023×10*23molecules/mol= 1.2044×10*25 molecules.

=> Thus, the options (ii) correctly represents 360 g of water.
