0.0733L of 3.00 M CH3COOH solution is needed to provide 0.220 mol of CH3COOH.
<u>Explanation</u>:
Molarity, M = moles of the molecule / Liter of solution
Therefore, we can work backwards to find the number of litres of solution, if we are given the number of moles
The values are a given as,
The molarity of the solution =3.00M
The final moles = 0.220 moles.
0.220 mol CH3COOH ( 1L / 3.00 mol CH3COOH) = 0.220/3.00
=0.0733L of solution
there are 4.0 moles of SO3
The answer Is D

The electronegativity of the element affects the ability of its compounds to dissolve in different solvents.
<h3>What is the meaning of electronegativity?</h3>
Electronegativity is a measure of an atom's ability to attract shared electrons to itself.
Polar bonds have a positive and negative side to them, and therefore can attract water dipoles and dissolve in water.
If the polarities of the solvent and solute match (both are polar or both are nonpolar), then the solute will probably dissolve.
If the polarities of the solvent and solute are different (one is polar, one is nonpolar), the solute probably won't dissolve.
Hence, option D is correct.
