Question

44. Explain what changes and what stays the same when 1.00 L of a solution of NaCl is diluted to 1.80 L.

Short answer

Molarity and volume of solution changes,

Moles of solute remains same.

Step-by-step solution

Step 1:

1 L solution of NaCl is prepared by dissolving some amount of NaCl solute in solvent that is water. On that amount of solute molarity of solution depends.

Step 2:

When the the 1 L solution is diluted to 1.80 L it’s volume changes.

Molarity = Moles of solute/ Liter of solution so molarity also change.

But moles of solute will remain same.
