Question

Find the number of moles and the number of atoms of Hydrogen and s in 10 moles of H₂S
​

Answer 1

See below

Step-by-step explanation:

H2 S shows that each mole of H2S has two moles of H in it

so 10 moles of H2S would have 20 moles of H

Each mole is Avagadro's Number of atoms

20 moles * 6.022 x10^23 atoms/mole = 120.44 x 10^23 toms of H

H2S has one mole of S for each mole of H2S

there are then 10 moles of S

10 * 6.022 x 10^23 = 60.22 x 10^23 atoms of S
