Answer #1

molarity of NaCl   = 2.1M

volume of solution = 1.2liters

no of moles of NaCl   = molarity*volume in L

                                  = 2.1*1.2   = 2.52moles

mass of NaCl         = no of moles * formula weight of NaCl

                               = 2.52*58.5   = 147.42g >>>>answer
