Answer :
Final answer:
Using the dilution equation M1V1 = M2V2, 10 liters of 0.3M HCl can be made from a 2L stock solution of 1.5M HCl. The correct answer is A.
Explanation:
The question is asking to calculate how many liters of 0.3M HCl can be made from a 2L stock solution of 1.5M HCl. To answer this, we can use the concept of dilution and the equation M1V1 = M2V2, where M1 and V1 represent the molarity and volume of the stock solution, and M2 and V2 represent the molarity and volume of the diluted solution, respectively.
By rearranging the formula to solve for V2, we get V2 = (M1V1) / M2. Plugging in our values, we have V2 = (1.5M * 2L) / 0.3M = 10L. Therefore, 10 liters of 0.3M HCl can be made from a 2L stock solution of 1.5M HCl, which corresponds to answer choice A.
