Answer:
0.250 mol Mg²⁺
0.500 mol Cl⁻
Explanation:
Magnesium chloride (MgCl₂) dissociates into ions according to the following equilibrium:
MgCl₂ ⇒ Mg²⁺ + 2 Cl⁻
1 mol 1 mol 2 mol
1 mol of Mg²⁺ and 2 moles of Cl⁻ are formed per mole of MgCl₂. If we have 0.250 mol of MgCl₂, the following amounts of ions will be formed:
0.250 mol MgCl₂ x 1 mol Mg²⁺/mol MgCl₂= 0.250 mol Mg²⁺
0.250 mol MgCl₂ x 2 mol Cl⁻/mol MgCl₂= 0.500 mol Cl⁻

Explanation:
Answer is 30.0mL
according to the question dilution is performed by the student which can be calculated with the help of :
EQUATION (1)
Here, we have:
= 3M
= y mL
= 1.80 M
= 50.0mL
putting the known values in equation (1) which will give us value of
3.00× y =1.80 ×50.0
y= 30.0mL
