10g of Sodium Chloride are dissolved in 200ml of H2O. What is the mass percentage of solute in

this solution?

3 answers

assuming the density of water 1000gr/L calculate mass of water and add 5.85gr
then %=mass of solute/mas of solution x 100
2•3%
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
