Question

Concentrated aqueous sulphuric acid is 98 percent h2so4 by mass

Answer 1

Answer:

molecular wieght h2so4 =98

suppose mixture is 100gm

then 98%is h2so4 and 2%h20

then % of h2so4 by mass

= 98×98÷100= 96.04

You have asked the incomplete question. The question is ' Volume of acid required to make 1L of 0.1M H2SO4 is __________ .

Here's your answer:

Concentrated aqueous sulphuric acid = 98% by weight means 98 gm. H2SO4 in 100 gm.  solution.

Number of moles = 98 / 98 = 1.

Density = 1.8 g/L

Volume of the solution = Mass of solution / Density = 100 / 1.8 = 55.55 mL = 0.055L.

We know that,

                =

               18 * V1 = 0.1 * 1000

By solving, we get, V1 = 5.55 mL.

Hope it helps you, please mark it as the brainliest.

Have a nice day..
