Answer:
The correct answer is 17 meq/g
Explanation:
Ion exchange capacity (IEC) express the total of active sites of a resin in which ions are attached because the greater molecular weight.
The exchange Reaction can be represented as
R-H
The IEC value (in meq/g) is determinated by using the next equation:
IEC=[(mL of NaOH)*(M of NaOH)]/mass of resin
IEC [(17 mL)*(0.5 M)/0.5]= 17 meq/g
You would be most likely to use a slicing machine if you were using the <u>icebox </u>method to produce cookies.
In the icebox method a type of cookie in which the dough is made, rolled into a stick, and refrigerated until the dough hardens. The dough can be removed from the refrigerator, cut into individual pieces, and then baked. The rest of the dough is returned to the refrigerator until needed.
Icebox method, also known as refrigerator cookies, are sliced and baked cookies. The dough is formed into logs, chilled in the refrigerator (also called an icebox), sliced , and then baked.

Answer:
0.28M
Explanation:
From the question given, we obtained the following information:
C1 = 1.1 M
V1 = 125mL
V2 = 500mL
C2 =?
Using the dilution formula C1V1 = C2V2, we can easily find the molarity of the diluted solution as follows:
C1V1 = C2V2
1.1 x 125 = C2 x 500
Divide both side by 500
C2 = (1.1 x 125)/500 =
C2 = 0.28M
