Question

QUESTION 1 You are given a solution that has 2.0 mole of NaCl in a 1.0 ter solution of water, and you add 1.0 lifter of water to this solution such that the volume becomes 2.0 iters? What happens to teh number of moles of NaCl in this solution? O The number of moles of NaCl in the solution increases by a factor of 2 The number of moles of Naa in the solution decreases by a factor of 2. O The number of moles of NaCI in the solution stays the same QUESTION 2 You are given a solution that has 2.0 mole of NaCI in a 1.0 liter solution of water, and you add 1.0 iter of water to this solution such that the volume becomes 2 0 sters? What happens to the concentration of NaCi? The molar concentration of NaCl increases by a factor of 2 O The molar concentration of NaCI decreases by a factor of 2. The molar concentration of Naci stays the same

Explanation / Answer

Ans 1 : The number of moles of NaCl in the solution stays the same.

Since the volume of solvent is only changed in the solution , the number of moles of NaCl has stayed unchanged. Though the molar concentration of the solution is now changed , as the volume of solution has now been increased.
