Question

if 2.86 moles of sodium hydroxide were added to water to create a solution that is 0.858 M, what is the volume of the solution?​

Answer 1

Molarity = moles of solute / volume of solution in liters

We are given the moles of solute (2.86 moles) and the molarity (0.858 M). Let's rearrange the formula to solve for the volume:

Volume of solution = moles of solute / molarity

Volume of solution = 2.86 moles / 0.858 M

Volume of solution = 3.33 L

Therefore, the volume of the solution is 3.33 liters.
