Answer:
pH = 2.5
Explanation:
Given data:
Concentration of HBr = 0.003 M
pH of solution = ?
Solution:
Formula:
pH = -log[H⁺]
by putting values,
pH = -log [ 0.003]
pH = 2.5
<u>Answer:</u> The volume of solution is 1.13 L
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

We are given:
Molarity of solution = 2.09 M
Given mass of silver nitrate = 400. g
Molar mass of silver nitrate = 170 g/mol
Putting values in above equation, we get:

Hence, the volume of solution is 1.13 L
The main difference between gas pressure and vapour pressure is that gas pressure is exerted by the gases above the surface of a substance whereas vapour pressure is exerted by liquids above the surface of a substance
