In 1L of a 3M solution of sodium chloride, how many grams of sodium chloride are in the solution?

Answer 1

Naomi Aronson

#"175.35 g"#

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.
