That is not the correct answer. Please check our notes again - we have moles in 25 mL of ACID, but that is NOT molarity, which is moles in one litér. how many times would we have to multiply this volume with its moles to fill 1000 mL?

To find the number of times you would need to multiply the volume and moles to fill 1000 mL, you need to first determine the molarity of the solution. Molarity (M) is defined as the number of moles of solute per liter of solution.<br /><br />Given:<br />- Volume of acid solution = 25 mL<br />- Moles of acid in 25 mL = \( x \) (unknown)<br /><br />First, convert the volume from mL to L:<br />\[ 25 \text{ mL} = 0.025 \text{ L} \]<br /><br />Now, calculate the molarity (M) using the formula:<br />\[ \text{Molarity (M)} = \frac{\text{moles of solute}}{\text{volume of solution in liters}} \]<br /><br />So,<br />\[ \text{Molarity (M)} = \frac{x}{0.025} \]<br /><br />To find out how many times you need to multiply the volume and moles to fill 1000 mL (1 L), you need to determine how many moles are required for 1 L of solution.<br /><br />Since molarity is the number of moles per liter, for 1 L of solution, the number of moles would be:<br />\[ \text{Moles for 1 L} = \text{Molarity} \times 1 \text{ L} \]<br /><br />Therefore, the number of times you would need to multiply the volume and moles to fill 1000 mL is simply the molarity, which is:<br />\[ \text{Number of times} = \frac{1 \text{ L}}{0.025 \text{ L}} = 40 \]<br /><br />So, you would need to multiply the volume and moles by 40 to fill 1000 mL.
