Cu + S → CuS (sulfuro cúprico)
Mm CuS = 95.61 g/mol
S = 32 g/mol
Cu = 63.54 g/mol
1. calcular moles de CuS
mol CuS = 64 g S x 1 mol S x 1mol CuS
```````````` ``````````````
32 g S 1mol S
mol CuS = 2
g CuS = 64 g S x 1 mol S x 1mol CuS x 95.61 g CuS
```````````` `````````````` ``````````````````
32 g S 1mol S 1 mol CuS
g CuS = 191.22
````````````````````````````````````````````````````````````````````````````````````````````````````
2Cu + S → Cu2S (sulfuro cuproso)
Mm = Cu2S = 159.15 g/mol
1. calcular moles de CuS
mol CuS = 64 g S x 1 mol S x 1mol CuS
```````````` ``````````````
32 g S 1mol S
mol CuS = 2
g CuS = 64 g S x 1 mol S x 1mol Cu2S x 159.15 g Cu2S
```````````` `````````````` ``````````````````````
32 g S 1mol S 1 mol Cu2S
g CuS = 318.3
NOTA: Lo resolvi con las 2 valencias del cobre, no indicas si es sulfuro cuprico o cuproso
