Given :
0.26 mole of and 0.35 L of water.
To Find :
The molarity of a solution of made by mixing 0.26 mole of potassium
phosphate with water up to 0.35 L .
Solution :
We know, molarity is given by :
Therefore, the molarity of solution is 0.743 M.
The term sulfate is used in chemistry to denote a salt of sulfuric acid. ... This is the sulfate type which can be found in many cleaning and hygiene products including shampoos. The main reasons why it is added to shampoos are because this sulfate produces foam and is a powerful detergent.
Explanation:
P1V1 = P2V2
(100.7 kPa)(0.75 L) = (99.8 kPa)V2
V2 = (100.7 kPa)(0.75 L)/(99.8 kPa)
= 0.757 L
<h2>Hello!</h2>
A sustainable practice is B. Setting usage limits on a resource
<h2>Why? </h2>
Sustainable practices are those that aim to reach an equilibrium between the use of natural resources for human development, and the preservation of the environment for future generations.
Setting usage limits on a resource is a sustainable practice because it allows for taking advantage of the resource, while providing constraints to its use, forcing the industry to be creative and develop alternative methods that take better advantage of that resource, or that use different resources (e.g. limiting fossil fuel emissions, forcing the industry to find alternative ways to generate power like solar energy).
Have a nice day!
