Answer:
An observation
Explanation: observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity
To solve the problem, use the equation
M1(V1) = M2(V2)
Where M1, M2 are the concentrations
V1, V2 are the volumes
Given V1 = 30.0 mL, M1 = 12.0 M
M2 = 0.16 M
Substituting to the equation,
(30)(12) = (V2)(0.16)
V2 = 2250 mL
