Question

Calculate the total number of moles of atoms in 980gram of h2so4

Answer 1

Aloha Mate,
Here is the desired answer..

Since, we know that no. Of moles of atom of any element is always equal to the given mass divided by the atomic mass of the given element..
I.E. The ratio of given mass to that of the atomic mass

Here, let's calculate the atomic mass of h2so4...

Since, mass of hydrogen =1 u
Mass of sulphur=32u
Mass of oxygen= 16u
Therefore, mass of h2so4 is 2+ 32+ (16×4)
=2+32+64
=98u
=98 gram

Now, putting that value in the formula(given mass upon atomic mass) we get,
980/98
=10 moles...

Therefore, the answer is 10 moles of atoms...

Hope it helps❣️❤️

Answer 2

●HEY MATE HERE IS YOUR ANSWER●

measure of H2SO4(W) = 980gram

and molar mass of H2SO4(M) =

( 1×2) + (32 ×1) + (16 × 4)

= 98u = 98gram

so the number of mole

= W/M

= 980/98

10 mol
