Answer to Question #23984 in Chemistry for Chris Cornelio

Question

How many hydrogen atoms are in 0.1731 mol of H2SO4?

Answer 1

H₂SO₄ includes two atoms of hydrogen,so we can write its like:

H₂SO₄ -----> 2H⁺ + SO₄^2-

One mole of compound consist of 6.02 *10^23 molecules. It is Avogadro constant. Now we can calculate hydrogen atoms:

0.1731 mol N
H₂SO₄ -----> 2H⁺ + SO₄^2-
1 2* 6.02 *10^23

N = (0.1731* 2* 6.02 *10^23 )/1 = 2.084 *10^23 atoms
