Answer #1

molarity of NaCl = 2.63mole/L

volume of solution = 290ml = 0.29L

no of moles of NaCl   = molarity * volume in L

                                   = 2.63*0.29   = 0.7627 moles

mass of NaCl             = no of moles * gram molar mass

                                 = 0.7627*58.5   = 44.62g >>>>answer
