Question

Calculate mass of Sulphur and no. of
atoms of sulphur in 98 grams of
Sulphuric Acid H2so4​

Answer 1

Answer:

molar mass of the sulphuric acid = 2+32+64

=. 98 gram/moles

Given mass of the sulphuric acid =196 gram

therefore number of molecules of the sulphuric acid = number of moles * avagadro number.

therefore number of the molecules of the sulphuricacid=2*6.022*10^23molecule

now one mole of the sulphuric acid contain one sulphuric acid.

therefore 12.044*10^23 molecules of the sulphuric acid contain 12.044*10^23 sulphur atom.

Answer 2

Experts, please do not delete my answer, this answer is from the answer which I gave earlier, I have copied and pasted from MY answer itself, There's no plagiarism or copy.

Here's the link to the original question = https://brainly.in/question/5093777

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..ooooooooo
