The Newman projection gives the view of the molecule. In molecule A the torsional strain and in B steric strain are present because of the gauche methyl group.
<h3>What is a torsional strain?</h3>
The Newman projection depicts the molecules in the head-on view and uses the letters and the lines to represent the molecule. The torsional strain is because of the molecule's resistance to the twisting.
The steric strain is the Vander wall strain that is due to the forced interaction of the molecules separated by covalent bonds resulting in molecular potential energy.
The diagram for the question is attached below.
Therefore, the correct blanks are <u>torsional</u>, <u>steric</u>, and <u>gauche</u>.

Sulfuro de calcio.
Answer:
The atomic mass of an atom is the number of protons plus neutrons.
Fact: In case you get it confused with atomic number, atomic number is the number of protons in the atom.
Explanation: It could have been electrons plus neutrons since electrons equals protons but electrons aren't stable which is why it is protons and neutrons.
If you mean hydrate as in <em>MgSO4 · 7H2O, </em>then simply find the molar mass of each element you see.
For the example above, that means you would add the molar mass (found on the periodic table) of Mg, then S, then 4(O), 14(H), and 7(O).
The results would be your molar mass for the hydrate.
