S + 2 Cu → Cu2S
Mm Cu2S = 159 g/mol
Cu = 63,54 g/mol
g Cu2S = 10 g S x 1 mol S x 1 mol Cu2S x 159 g Cu2S
```````````` ```````````````` ````````````````
32 g S 1 mol S 1 mol Cu2S
g Cu2S = 49, 68 g
b)
mol Cu2S = 10 g S x 1 mol S x 1 mol Cu2S
`````````` ````````````````
32 g S 1 mol S
mol = 0.3125 de Cu2S
Mm Cu2S = 159 g/mol
Cu = 63,54 g/mol
g Cu2S = 10 g S x 1 mol S x 1 mol Cu2S x 159 g Cu2S
```````````` ```````````````` ````````````````
32 g S 1 mol S 1 mol Cu2S
g Cu2S = 49, 68 g
b)
mol Cu2S = 10 g S x 1 mol S x 1 mol Cu2S
`````````` ````````````````
32 g S 1 mol S
mol = 0.3125 de Cu2S
