In the world's oceans, the average NaCl concentration is about 0.51 M. How many grams of NaCl would be in 1.0 liter of sea water?

NaCl MW = 58.442 g/mole
0.51M = 0.51 moles/liter = 0.51 moles/liter * 58.442g/mole
= 29.8 g/liter NaCl

0.51 M means 0.51 mol per liter of solution (seawater). So 1 L seawater has 0.51 mol NaCl. Just convert mol to grams.

NaCl Mol.mass = 23 + 35.5 = 58.5g/mol
0.51mol/L x 58.5g/mol. = 29.84g/L concentration.

0.51*58.5=29.8g/l (58.5 is molecular weight of NaCl)
