The molecular mass of H2SO4 is 98 u. calculate the number of each element in 294 grams of sulphuric acid.
I think I now the answer.
Molecular mass of H2SO4 = 98u
In which H is 2g , s is 32g and o is 64g
Given mass of H2SO4 = 294g
To find the mass of each element first divide the given mass by the molecular mass
given mass / molecular mass = 294 / 98 =3 moles
There is 3 moles of each element presentin 294g
ThereforeH = 3 *2 = 6g
S = 3 * 32 = 96g
O =3 * 64 = 192g
Thumbs up if my answer is correct.Ifnot then please do write the correct answer
