Answer:
Explanation:
1 mol of anything is 6.02 * 10^23 atoms (in this case)
x mol of 3.01 * 10^22
Set up the proportion
1/x = 6.02*10^23 / 3.01 * 10^22 Cross multiply
x*6.02 * 10^23 = 1 * 3.01 * 10^22 Divide by 6.02*10^23
x = 3.01 * 10^22 / 6.02*10^23
x = 1/(2 * 10)
x = 1/20 mol
x = 0.05 mol
It is the periodic table

The answer is group 1A.
In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.
Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.
Hence, X must belong to the 1A group.
Ionic Compounds-
- Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
- Cations are positively charged ions that are formed due to the loss of electrons.
- And the anions are negatively charged ions that are formed due to the gain of electrons.
- Due to this, they have opposite charges and form bonds known as Ionic Bond.
