A mineral contains only a metal, M, and sulfur. If analysis indicates that a 4.3 g sample of the mineral contains 1.56 g of M, what mass of M (g) is contained in 396 g of the mineral? Enter your answer in decimal format with two decimal places and no units.

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 =

396 g of mineral contains metal =

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