Sea water contains roughly 28.0 g of nacl per liter. What is the molarity of sodium chloride in sea water?

The molarity of sodium chloride in sea water is 0.479 M

Explanation:

Step 1: Data given

Mass of NaCl = 28.0 grams

Molar mass NaCl = 58.44 g/mol

Step 2: Calculate moles

Moles NaCl = mass NaCl / molar mass NaCl

Moles NaCl = 28.0 grams / 58.44 g/mol

Moles NaCl = 0.479 moles

Step 3: Calculate molarity NaCl in sea water

Molarity = moles / volume

Molarity NaCl = 0.479 moles / 1L

Molarity of NaCl in sea water = 0.479 mol/L = 0.479 M

The molarity of sodium chloride in sea water is 0.479 M
