Question

Please answer the above question with explaination❣️​

Answer 1

Answer:

M= (W (gm) ×1000) / (V(ml)×m(gm))

W= wt. of solute =1.25g

V= Volume of solvent =25mL

M= Molarity of solvent =0.25M

m= mol. wt. of solute =?

∴0.25=

25×m

1.25×1000

⇒m=200gm

Hence the molecular mass of acid is 200 gm.
