Answer:
0.36g of Al
0.64g of S
Explanation:
Let us write a balanced equation for the decomposition of aluminium sulfide Al2S3. This is shown below:
Al2S3 —> 2Al + 3S
Molar Mass of Al2S3 = (2x27) + (3x32) = 54 + 96 = 150g/mol
Molar Mass of Al = 27g/mol
Mass of Al from the balanced equation = 2 x 27 = 54g
Molar Mass of S = 32g/mol
Mass of S from the balanced equation = 3 x 32 = 96g
Now we can obtain the mass of Al and S produce as follows:
For Al:
From the equation,
150g of Al2S3 produced 54g of Al.
Therefore, 1g of Al2S3 will produce = 54/150 = 0.36g of Al.
For S:
From the equation,
150g of Al2S3 produced 96g of S.
Therefore, 1g of Al2S3 will produce = 96/150 = 0.64g of S
