What volume would a 1.15 molar solution of potassium nitrate need to make 0.75 moles of potassium nitrate?

Answer 1

Hi Camila:

Just as for the question before, you must use the following formula,

Molarity = # moles

# L

or

M = n

V

For this equation, V is always in Liters (L).

From the problem statement, you have M and n, so you can solve for V. Remember that this volume is in Liters. You can always convert to mL if needed.
