How many grams of aluminum hydroxide are obtained from 16.2 g of aluminum sulfide?

Biology
1 answer:
nadezda [96]3 years ago
8 0
Number of moles Aluminium sulfide
1 mole of sulfide contains 150 g
Therefore; 16.2/150 
               = 0.108 moles 
The mole ratio of Al2S3 : Al(OH)3 is 1:2
Therefore; moles of Aluminium hydroxide will be;
  = (0.108 × 2)
  = 0.216 moles 
But, 1 mole of  Al(OH)3 contains 77 g
Therefore, the mass of aluminium hydroxide is
   0.216 moles × 77
=  16.632 g

Non example of mitochondrion
Yuliya22 [10]
The number of mitochondria per cell varies widely; for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.
