Question

Concentrated aqueous sulphuric acid is 98% h2so4 w/v and has density 1.8g/ml. The molarity of the solution is

Answer 1

First you determine the molarity of te H2SO4 (and note that you made a typo). The density of conc H2SO4 is 1.80 g/mL (not 1.80 g/L).

mass H2SO4 in 1L = 1000 mL x 1.80 x 0.98 = ?

Then mols = grams/molar mass and since that's the mols in 1L soln that is the molarity.

For the dilution use the dilution formula which is c1v1 = c2v2 where

c = concn

v = volume

pls mark as brainliest .........

Answer 2

Answer:

Explanation:

ans-98% means 98g in 100ml

Molarity=(Mass/Molar mass)/(Volume of solution in litres)

Hope you understood.
