WHO IS GOOD AT CHEMISTRY EQUATIONS? I NEED A QUESTION ANSWERED BY TONIGHT! ITS THE ONLY ONE IM STUCK ON:

Consider the chemical formula for one unit of aluminum sulfate, Al2(SO4)3. How many total atoms would be present in 22 units of aluminum sulfate?

374 atoms would be present in 22 units of aluminum sulfate.

Explanation:

Formula for Aluminium Sulfate :  Al₂(SO₄)₃

Al = 2

S = 1

O = 4

(SO) = 3

∴ Number of atom in one unit is :  2 + (1+4)3 ==> 17

If there are 17 atoms in one unit, therefore;

Number of atoms in 22 units = 17 x 22

                                                = 374 atoms

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
