x = 20 long tables
y = 5 round table
Explanation:
We have the following system of equations:
x + y = 25
8x + 6y = 190
From the first equation we have:
x = 25 - y
And we replace x in the second equation:
8(25 - y) + 6y = 190
200 - 8y + 6y = 190
200 - 2y = 190
200 - 190 = 2y
10 = 2y
y = 5
Now we insert the value of y in the next equation:
x = 25 - y
x = 25 - 5
x = 20

Answer:
Name of the compound is aluminum sulphate. chemical formula Al2(SO4)3
In that compound there are two aluminum atoms; three sulphur and 4*3=12 oxygen atoms.
2 oxygen atoms is equivalent to 1 mole oxygen.
so 12 oxygen is equivalent to 12÷2=6 mole oxygen.
