Answer:
There will 3.95 grams of Na2 and H2O that should be added to form a concentric required solution.
C. Increases. Increasing temperature=Increasing Volume
2.2 x 10^-2
0.055 / 250 = 0.00022 - This would be 2.2 x 10^-4, but the question is asking for percent, not proportion, so multiply by 100% to get the percentage.
0.00022 * 100% = 0.022% = 2.2 * 10^-2
