You must add 7.5 pt of the 30 % sugar to the 5 % sugar to get a 20 % solution.
You can use a modified dilution formula to calculate the volume of 30 % sugar.
<em>V</em>_1×<em>C</em>_1 + <em>V</em>_2×<em>C</em>_2 = <em>V</em>_3×<em>C</em>_3
Let the volume of 30 % sugar = <em>x</em> pt. Then the volume of the final 20 % sugar = (5 + <em>x</em> ) pt
(<em>x</em> pt×30 % sugar) + (5 pt×5 % sugar) = (<em>x</em> + 5) pt × 20 % sugar
30<em>x</em> + 25 = 20x + 100
10<em>x</em> = 75
<em>x</em> = 75/10 = 7.5
The properties of malleability and ductility can all be explained on the basis of metallic bonding.
<h3>What is malleability?</h3>
The term malleability refers to the ability of a metal to be hammered into sheets. It is a very important property of metals that helps in metal work. The images are not shown here hence the question is incomplete.
Ductility refers to the ability of metals to be drawn into sheets. This is the reason why metals can be used to make wires. All these properties are explained on the basis of metallic bonding.
