A way to protect iron corrosion is to paint the Iron with layers of protective paint and coating.
The volume of the stock solution needed is 213.88 mL to get new concentration.
<h3>What is molarity?</h3>
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution.
Determination of the volume of stock solution.
Volume of diluted solution (V₂) =550 mL
Molarity of diluted solution (M₂) =0.70 M
Molarity of stock solution (M₁) = 1.8 M
Volume of stock solution needed (V₁) =?
M₁V₁ = M₂V₂
1.8 M × V₁ = 0.70 M × 550 mL
V₁ = 213.88 mL
Thus, the volume of the stock solution needed is 213.88 mL.

Magnesium oxide : MgO
Calcium bicarbonate: Ca(HCO3)2
aluminum carbonate: Al2(CO3)3 or C3Al2O9
(16.3 L) / (22.414 L/mol) x (4.0026 g He/mol) = 2.91 g
