Question

4. According to Reference Table G, how many grams of KNO3 would be needed to saturate 200 grams of
water at 70°C?
(1) 43 g
(2) 86g
(3) 134 g
(4) 268 g

Answer 1

Answer:

The answer is choice (4) 268 g.

Explanation:

To find this answer you have to go to the reference table, using Table G, and go to KNO3 at 70°C. Find out how many grams saturate potassium nitrate (134 g). Then you double it (268 g ) because it's asking for grams at 200 grams of water.
