Question

calculate the molarity of a solution containing
5g of
NaOH in 450 ml solation​

Answer 1

molar mass of NaOH=40g per mole

molar mass of NaOH=40g per moleno. of moles in 5g of NaOH=5/40=0.125

molar mass of NaOH=40g per moleno. of moles in 5g of NaOH=5/40=0.125volume of solution=450mL=0.45L

molar mass of NaOH=40g per moleno. of moles in 5g of NaOH=5/40=0.125volume of solution=450mL=0.45Lmolarity of solution=no.of moles of solute/volume of solution

molar mass of NaOH=40g per moleno. of moles in 5g of NaOH=5/40=0.125volume of solution=450mL=0.45Lmolarity of solution=no.of moles of solute/volume of solution =0.125/0.45

molar mass of NaOH=40g per moleno. of moles in 5g of NaOH=5/40=0.125volume of solution=450mL=0.45Lmolarity of solution=no.of moles of solute/volume of solution =0.125/0.45 =0.277777777778=0.28(approx.)
