The most abundant element dissolved in sea water is chlorine at a concentration of \( 19 \mathrm{~g} / \mathrm{kg} \) of sea
\( \mathrm{P} \) water. The volume of earth's ocean is \( 1.4 \times 10^{21} \mathrm{~L} \).

How many g-atoms of chlorine are potentially available from the oceans? The density of sea water is \( 1 \mathrm{~g} / \mathrm{ml}\left(N_{\mathrm{A}}=6 \times 10^{23}\right) \).
(a) \( 7.5 \times 10^{20} \)
(b) \( 27 \times 10^{21} \)
(c) \( 27 \times 10^{24} \)
(d) \( 7.5 \times 10^{19} \)
