3 moles of HCl=?? Molecules of H2

Answer 1

Hello, Raven,

3 moles of HCL = 3 moles of H.

Moles H₂ would be half that number, since there are two H per molecule. H₂ = 1.5 moles,

One mole is 6.02x10²³ molecules/mole

Therefore, we have (1.5 moles H₂)*(6.02x10²³ molecules H₂/mole H₂) = 9.03x10²³ molecules of H₂
