Final answer:
To obtain 6.00 moles of HCl from a 7.50 M solution, one would need 0.80 liters of the solution. The given answer options do not include 0.80 L, suggesting a potential error in the options provided.
Step-by-step explanation:
The student asked to calculate the liters of a 7.50 M HCl solution needed to obtain 6.00 moles of HCl. To find the volume of the solution, we use the formula:
Molarity (M) = Moles of solute (mol) / Volume of solution (L)
Rearranging the formula to solve for the volume gives us:
Volume of solution (L) = Moles of solute (mol) / Molarity (M)
Substitute the given values into the equation:
Volume of solution (L) = 6.00 moles of HCl / 7.50 M
Volume of solution (L) = 0.80 L
Therefore, 0.80 L (or 800 mL) of the 7.50 M HCl solution is required to have 6.00 moles of HCl. This matches option b) 0.80 L, which is not explicitly listed in the provided options. Therefore, there may be a mistake in the given options or the question.
