Question

a) concentration of naoh Solution is 10 %Wlv
molatity (d=1.2g​

Answer 1

Answer:

Here if an 100 g of an diluted NaOH solution is marked as 10%(w/w) of NaOH then W2(mass of solute)=10g and mass of water(W1)=90g.

density=Vsolutionmass

Vsolution=1.070100=93.46cm−3=0.09346L

number of moles of NaOH(nsolute)=49g(mol)−110g=0.2mol

Molarity=Vsolutionnsolute

Molarity=0.09346L0.2mol=2.14M

molality=W1(inkg)nsolute

molality=0.09kg0.2mol=
