The best option is a. but it is not complete!
Both liquids have different densities, it's true. But they are immiscible liquids and they don't form a solution.
200.0 mL =0.2000 L
Molarity = number of mole solute / volume solution(L) = 0.50 mol/0.2000 L=
= 2.5 mol/L =2.5M
Answer : 2.5 M
Answer:
Problem, Variables, Hypothesis, Research, Procedure, Data, Conclusion.
Explanation:
First, you have to know what the problem that you're talking about is. Then, you have to know the independent, dependent, and controlled variables are in order to make a hypothesis. Then do research about the topic. After that, you make the procedure your experiment, if that's what your doing. Then after the experiment, you find the data. Using that data, you make a conclusion.
The physical science unit of criminal investigation applies principles and techniques of chemistry, physics, and geology to the identification and comparison of crime scene evidence.
<h3>What is forensics in criminal investigation?</h3>
Forensics science is any of several fields of study involving the collection of physical evidence and its subsequent analysis.
The aim is to use of science and technology in the investigation and establishment of facts or evidence in a court of law.
There are several units involved in forensics science such as the following;
- Biology unit
- Physical science unit
The physical unit of forensics is the unit that applies principles & techniques on chemistry, physics and geology, which are physical science fields, to identify and compare crime scene evidence.
