# Find in 98g of h2so4: no. of h atoms​

9

Explanation:

Molecular mass of H2SO4 is 98 gm.

So if you are asking no. Of moles of Hydrogen gas (H2) then one mole of hydrogen gas will contain two mole of hydrogen atoms.Now since 1 molecule of H2SO4 contain two hydrogen atoms thus 1 molecule of hydrogen gas (H2). Therefore 98 gm(1mole) of H2SO4 will contain one mole of H2 gas. And two moles of Hydrogen atoms.

Given: 98 grams of H2SO4

To find: Number of Hydrogen (H) atoms

Explanation: Given mass of H2SO4= 98 grams

Molar mass of H2SO4

= 2 * molar mass of H + 1* molar mass of S+ 4* molar mass of oxygen

= 2*1 + 1*32 + 4*16

= 98 grams/ mol

Number of moles of H2SO4

= Given mass / molar mass

= 98 / 98

= 1 mole

Therefore, there is 1 mole of the compound H2SO4.

1 mole of H2SO4 contains 2 moles of H atoms.

Therefore, number of H atoms

=

=

Therefore, there are H atoms in 98 grams of H2SO4.
