Question

Calculate molecular mass of following
1. CS2
2. Al2O3
Please answer with solution

Answer 1

Answer:

Explanation:

1) CS2 =

carbon = 12g

Sulphur = 32*2 = 64g

64g + 12g = 76g

2) Al2O3

aluminum = 27*2 = 54g

oxygen = 16*3 = 48g

54+ 48 = 102g

Answer 2

Answer:

1) CS2 =

CARBON = 12g

SULPHUR = 32*2 = 64g

64g + 12g = 76g

thus,molecular mass of CS2 is 76g

2) Al2O3

aluminum = 27*2 = 54g

oxygen = 16*3 = 48g

54+ 48 = 102g

thus,molecular mass of Al2O3 is 102g
