Question

how many moles of Hydrogen atoms are there in 0.5 mol of sulphuric acid ​

Answer 1

Answer:

According to Avagadro’s law 1 mole of any substance contains 6.022×1023 molecules so in our case 1/2 moles of sulphur contains 1/2×6.022×1023 atoms.

I.e 3.011×1023 atoms are present in 0.5 moles of H2SO4

Explanation:

hope u got it

Answer 2

Given :0.5 moles of sulphuric acid

To find: number of moles of hydrogen present in sulphuric acid

Solution:

Sulphuric acid has chemical formula that is H2SO4 contains 2 hydrogen atoms

Sulphuric acid has chemical formula that is H2SO4 contains 2 hydrogen atomsWe know ,

AVOGADRO NUMBER FOR ONE MOLE OF ANY SUBSTANCE I= 6.022× 10²³

1mole of H2SO4 have 2 hydrogen atom

Number of moles of hydrogen present in 0.5 moles of h2SO4 is

= 0.5 × 6.022 × 10²³×2

= 1× 6.022× 10²³ (0.5×2=1)

=6.022×10²³

Answer : 6.022×10²³ moles of hydrogen atoms are there in 0.5 mol of sulphuric acid.
