Answer:
22.95g
Explanation:
Given parameters:
Percentage by mass of silver in silver iodide = 45.9%
Mass of silver iodide given = 50g
Unknown:
Mass of silver in silver iodide = ?
Solution:
The formula of the compound is;
Silver iodide = AgI
Since the percentage by mass of silver in the compound is 45.9%;
Mass of silver = percentage by mass of silver x mass of AgI
Mass of silver = x 50 = 22.95g
Answer:
new solubility = 0.443 g/l
Explanation:
To solve this question, we will use Henry's law.
Henry's law states that, at constant temperature:
S1 / P1 = S2 / P2
We are given that:
S1 = 0.16 g/l
P1 = 104 kPa
S2 is the solubility we want to calculate
P2 = 288 kPa
Substitute with the givens in the above relation to get the new solubility (S2) as follows:
0.16 / 104 = S2 / 288
S2 = (0.16/104) * 288
S2 = 0.443 g/l
