Answer:Sol. P base 1 = 10 kpa = 10 × 10^3 pa. P base 2 = 50 × 10^3 pa. v base 1 = 200 cc. v base 2 = 50 cc (i) Work done on the gas = ½ (10+50) ...
Explanation:
There are several ways of expressing concentration of solution. Few of them are listed below
1) mass percentage
2) volume percentage
3) Molarity
4) Normality
5) Molality
In most of the drugs, concentration is expressed either in terms of mass percentage or volume percentage. For, solid in liquid type systems, mass percentage is convenient way of expressing concentration, while for liquid in liquid type solutions, expressing concentration in terms of volume percentage is preferred. Present system is an example of liquid in liquid type solution
Here, concentration of H2O2 is given antiseptic = 3.0 % v/v
It implies that, 3ml H2O2 is present in 100 ml of solution
Thus, 400 ml of solution would contain 4 X 3 = 12 ml H2O2
The molarity of Ba(OH)₂ barium hydroxide solution is 0.41 M.
<h3>What is
Molarity ?</h3>
Molarity (M) is the amount of a substance in a certain volume of solution.
Molarity is defined as the moles of a solute per liters of a solution.
Molarity is also known as the molar concentration of a solution
It can be written as
The given data is
Mass of Ba(OH)₂ = 3 g
Volume of solution = 42.8 ml = 0.0428 l
Molecular weight of Ba(OH)₂ = 171 g
Moles of Ba(OH)₂ = 3/ 171 = 0.0175 moles
Molarity = 0.0175/0.0428
=0.41 M
Therefore the molarity of Ba(OH)₂ is 0.41 M.
