Respuesta :

Answer: 143.66 grams of M (g) is contained in 396 g of the mineral

Explanation:

Given : mineral contains metal M and sulphur

Mass of mineral = 4.3 g

Mass of metal M in mineral = 1.56 g

Thus if 4.3 gram of mineral contains metal = 1.56 g

Using unitary method for solving this :

1 g of mineral contains metal =[tex]\frac{1.56}{4.3}\times 1=0.36[/tex]

396 g of mineral contains metal =[tex]0.36\times 396=143.66 g[/tex]

Thus 143.66 grams of M (g) is contained in 396 g of the mineral
