The length of each of the links in centimeter is 6.1 cm.
<h3>What is the length of a single chain link?</h3>
When we measure, we tend to obtain the value that represents the magnitude of the measurement. In this case, the magnitude of the length of the entire chain could all be obtained as see to be the value of 0.061km as it has been given on the question above.
Now, we have been told also that the surveyor measures the length of a surveying chain containing 1000 chain links. This implies that the length of a single chain link in centimeters is to be obtained by;
0.061 * 10^ 5/1000
= 6.1 cm

This reaction is called a composition reaction.
The rule that we will use to solve this problem is:
M1V1 + M2V2 + M3V3 = MtVt
where:
M1 is the molarity of first solution = 0.003 molar
V1 is the volume of the first solution which is the X that we want to find
M2 is the molarity of second solution = 0.0001 molar
V2 is the volume of second solution = 20 ml
M3 is the molarity of third solution = 0.002 molar
V3 is the volume of the third solution = 30 ml
Mt is the final total molarity = 0.0015 molar
Vt is the final volume = V1+V2+V3 = X+20+30 = (X+50) ml
Substitute with the above givens in the equation to get X as follows:
0.003X + 0.0001(20) + 0.002(30) = (X+50)(0.0015)
0.003X + 0.062 = 0.0015X + 0.075
0.003X - 0.0015X = 0.075 - 0.062
0.0015X = 0.013
X = 0.013 / 0.0015
X = 8.667 ml
