how many oxygen atoms are in 10 formula of Al2(SO4)3

To determine the number of oxygen atoms in 10 formula units of Al2(SO4)3, we need to consider the number of oxygen atoms in one formula unit and then multiply it by 10.

In the chemical formula Al2(SO4)3, there are three sulfate (SO4) groups. Each sulfate group contains one sulfur atom (S) and four oxygen atoms (O).

So, multiplying the number of oxygen atoms in one sulfate group by three will give us the total number of oxygen atoms in one formula unit of Al2(SO4)3. Then, multiplying this result by 10 will give us the answer for 10 formula units.

Let's calculate it step by step:

Number of oxygen atoms in one sulfate group = 4

Number of oxygen atoms in one formula unit of Al2(SO4)3 = 4 x 3 = 12

Number of oxygen atoms in 10 formula units of Al2(SO4)3 = 12 x 10 = 120

Therefore, there are 120 oxygen atoms in 10 formula units of Al2(SO4)3.
