Answer:
We take 20.0 mL of the 1.0 M fruit drink solution and then add 80.0 mL of water to make 100 mL of a 0.2 M fruit drink solution.
Explanation:
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 1.0 M, V before dilution = ??? mL.
M after dilution = 0.2 M, V after dilution = 100 mL.
<em>∴ V before dilution = (MV) after dilution / M before dilution </em>= (0.2 M)(100 mL) / (1.0 M) = <em>20.0 mL.</em>
<em>So, we take 20.0 mL of the 1.0 M fruit drink solution and then add 80.0 mL of water to make 100 mL of a 0.2 M fruit drink solution.</em>
The volume of the 1.0 M juice solution is 20 mL.
Concentration of juice =
Volume of the juice =
Concentration of Juice we need = 0.2
Volume of the 0.2 M juice we need
Using dilution formula :
We have to add 80 mL of water to 20 ml of solution which has concentration of juice equal to 1.0 M.
Q.1-
Given,
mass - 10grams
volume - 24 cm³
density = mass/volume
density = 10/24
density = 0.416 g/cm³
Q.2-
mass - 700grams
volume - 1100cm³
density = 700/1100
density = 0.6363 g/cm³
