Question

Typical seawater contains 2.7g of salt (sodium chloride, NaCl)per 100 ml.

What is the molarity of NaCl in the ocean؟

Answer 1

below

Step-by-step explanation:

2.7 g per 100 ml is th same as 27 g per liter

Molar weight of Na Cl

Na = 22.99 g/mole Cl = 35.45 g/mole Total= 58.44 g/mole

then 27 g is 27/ 58.44 = .462 moles per liter

which is .462 molar
