Answer:
0.2M
Explanation:
Data obtained from the question include:
C1 = 2.0 M
V1 = 100mL
V2 = 1000mL
C2 =?
Using the dilution formula C1V1 = C2V2, the molarity of the diluted solution can be obtained as follows:
C1V1 = C2V2
2 x 100 = C2 x 1000
Divide both side by the 1000
C2 = (2 x 100) / 1000
C2 = 0.2M
The molarity of the diluted solution is 0.2M
The manufacturing process shown in the photograph is d)Separating.
The cutting process in metals is a process where a piece of metal is cut into a desired shape or size. This can be done using a variety of methods, but the most common method is using a cutting tool. This eventually lead to the separation of the metals
Cutting processes are operations in which the work piece is cut into smaller pieces using power-driven cutting tools. A variety of cutting processes are used in metalworking, including machining, broaching, sawing, shearing, and abrading.
Each process has advantages and disadvantages, and the best process to use depends on the work piece material, the work piece geometry, and the desired tolerances.
Through these tools, the metals could be cut and separated easily. Hence the correct answer is option d)
