Answer 1

Answer:

I have to prepare a solution of 100ml 0,5N Phosporic Acid from 85% Phosporic acid,that I already have.

Following the formula W= XEV/1000, I would have the following:

XEV/1000= 4,8985 gm --> (being X=Molarity or Normality; E=97.97; V=100)

Vol= 4,8985/1,685= 2,907 ml --> (V=mass/density)

Would it be proper to add this volume of 85% Phosporic acid and water up to the desired final volume of 100ml?
