Question

How will you prepare 10%NaOH and calculate molarity of 10% of NaOH​

Answer 1

Answer:

10gNaOH dissolve in 100g solution or 19g naOH is prepared in (100-10)=90g of water

therefore weight of NaOh ÷10g mol% wt . of NaOH =10/40= 1/4 =0.25

weight of solvent ( water ) =90g

mortality (m)

moles of NaOH ×1000 / wt. of water (in gram )

0.25 ×1000/90 = 2.778
