Answer:
concentration of solution = 10.44%
step by step explanation
mass of solute = 70 g
mass of solvent = 600 g
then mass of solution = mass of solute + mass of solvent
= 70 + 600
670 g
conventration of solution = mass of solute/mass of solution × 100
= 70/670 × 100
= 70/67 × 10
= 10.44%

mass percentage concentration of naclin
=(mass of naclin/mass of naclin+mass of water)×100
= (70000/70000+600)×100
=70000/706
=99.1%
same process is for percentage of water
