Question

Calculate abundance of oxygen in aluminium sulphate

Answer 1

Explanation:

To calculate the percentage of oxygen in aluminum sulfate, , we need to determine the molar mass of this salt. The atomic masses of aluminum (Al), sulfur (S) and oxygen (O) are 27, 32 and 16, respectively. Thus, oxygen contributes about 56% of mass to aluminum sulfate.
