In 1L of a 3M solution of sodium chloride, how many grams of sodium chloride are in the solution? Chemistry Solutions Molarity 1 Answer MM · Stefan V. Apr 5, 2017 Answer: #"175.35 g"# Explanation: A #"3 M"# solution has #3# moles of solute per litre. The mass of one mole of #"NaCl"# equals the MW of #"NaCl"# #"MW" = 35.45 + 23 = "58.45 g/mol"# The mass of #3# moles is #"58.45 g/mol" xx "3 mol" = "175.35 g NaCl"# or #"200 g"# rounded to one sigfig.
