Molar mass of NaOH=40g per mole no. of moles in 5g of NaOH=5/40=0.125 volume of solution=450mL=0.45L molarity of solution=no.of moles of solute/volume of solution                               =0.125/0.45                               =0.277777777778=0.28

Molar mass of NaOH=40g per mole
no. of moles in 5g of NaOH=5/40=0.125
volume of solution=450mL=0.45L
molarity of solution=no.of moles of solute/volume of solution
                              =0.125/0.45
                              =0.277777777778=0.28(approx.)
