Answer:
D. The volume of the solvent used was less than 5 liters.
Explanation:
- We have the rule: the no. of moles before dilution equal the no. of moles after dilution.
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 10.0 M, V before dilution = V of stock = ??? L.
M after dilution = 1.0 M, V after dilution = 5.0 L.
<em>V before dilution = V of stock = (MV) after dilution/M before dilution</em> = (1.0 M)(5.0 L)/(10.0 M) = <em>0.5 L.</em>
∴ The volume of the stock used is 0.5 L.
The volume of the solvent used is 4.5 L.
<em>D. The volume of the solvent used was less than 5 liters.</em>
Fats and oils are two lipids that store energy
