(a)
Interpretation:
The molar masses of molecules are given by using chemical formula to be calculated.
Concept introduction:
Molar mass is also known as molecular weight, which is the sum of the total mass in grams of all the atoms that present in a particular molecule. If we know the formula of a compound then we can easily determine the compound’s molar mass. We know that a formula consists of atoms and it is important to count atoms carefully, especially in compounds with polyatomic ions enclosed in parentheses.

- Draw the mechanism for the following reaction: CH3 CH3 Et-OH Et Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP.
