Respuesta :

use the equation: Nm = M x Av
                             Nm = Moles x Avogadro constant
                             Nm = 6 x 6.02x10²³
                             Nm = 3.612x10²⁴

so in six moles of H2S there are 3.612x10²⁴ molecules

hope that helps  
To calculate the number of molecules in 6.00 moles of hydrogen sulfide, H2S, the equivalence factor used is Avogadro's number equal to (6.022 x 10^23 molecules/mole). The answer is 6.00 moles of hydrogen sulfide * (6.022 x 10^23 molecules/mole) equal to 3.61 x10^24 molecules.
