this solution?
Answers
Lennin
assuming the density of water 1000gr/L calculate mass of water and add 5.85gr
then %=mass of solute/mas of solution x 100
then %=mass of solute/mas of solution x 100

Mr(NaO)=23+16=39g.mol
C=m\mv
10g\39times0.2dm^3
=1.28mol.dm^3
I was just calculating the concentration of NaO in water
