Molarity= moles of solute/Liters of solution

#"1.55 M" = "moles"/".5"#

#"moles = 0.775 moles of NaCl"#

#"Molarity" = "moles of solute"/"Liters of solution"#

First, we need to convert #"500 mL"# to Liters

#"500 ml" * "1 L"/"1000 ml" = ".5 L"#

Now we can plug into our formula

#"1.55M" = "moles"/".5"#

#"moles = 0.775 moles of NaCl"#
