Question

The relative atomic mass of aluminium is 27 and of oxygen is 16. The aluminium ore shown below contains 5. 4kg of aluminium and 4. 8kg of oxygen. What is the value of x?

Answer 1

Answer:Hope this helps :D

Step-by-step explanation:

Cu = 27, S = 16 and O = 25.92

relative formula mass = 27 + 16 + (5.4x4.8) = 286.216

only one aluminum atom of relative atomic mass

64 % Cu = 100 x 64 / 160

x = 1036.8
