1L = 1000ml
1ml = 1cm^3
2.1L = 2100mL = 2100cm^3

Answer: Assume that the substance is hazardous. Always wear appropriate PPE and take steps to prevent contact.
Explanation:
When working with chemicals, a sound safety policy involving the use of chemicals should be established and maintained. This will help in safeguarding lives, properties and the environment.
The best safety approach when working with unknown chemical substances is to assume that the substance is hazardous and always wear appropriate PPE and take steps to prevent contact.
Since the substance is unknown, the best thing the person can do is to assume that it's harmful and hazardous and therefore take necessary precautions. The individual can put on laboratory coats, protective glasses, gloves etc. This is vital in order to prevent accidents from happening.
<u>Answer</u>:
Atoms of every element are shown in a skeletal model of an organic molecule.
<u>Explanation</u>:
Skeletal model of an organic molecule consists of various skeletal atoms that are used in making up of the molecule. Various conventions of hydrogen and carbon atoms are employed in it. The molecules bonding and certain representation of molecular geometry are shown in the structural formula.
Use of skeletal formula is ubiquitous in organic chemistry. Thus, in organic chemistry atoms of every element are shown in the skeletal model of an organic molecule
