Explanation of how to find the molar mass of Ca(C2H3O2)2: Calcium acetate.

A few things to consider when finding the molar mass for Ca(C2H3O2)2:

– make sure you have the correct chemical formula.
– always include the units for molecular weight (grams/mole).
– make sure you do the math right – follow the order of operations.

Note that molecular weight, molar mass, and gram formula mass are all the same thing.

Finding the Molar Mass (sometimes called Molecular Weight although the units are different) of a compound is a essential skill for the chemistry topic of stoichiometry and the first step in converting from moles to grams (or grams to moles).

How to Write the Formula for Calcium acetate

In this video we’ll write the correct formula for Calcium acetate: Ca(CH3COO)2.

To write the formula for Calcium acetate we’ll use the Periodic Table, a Common Ion Table, and follow some simple rules.

Because Calcium acetate has a polyatomic ion (the group of non-metals after the metal) we’ll need to use a table of names for common polyatomic ions, in addition to the Periodic Table.

Keys for Writing Formulas for Ternary Ionic Compounds:

1. Write the element symbol for the metal and its charge using Periodic Table.
2. Find the name and charge of the polyatomic ion on the Common Ion Table (see https://youtu.be/N4N1Njh7nCo).
3. See if the charges are balanced (if they are you’re done!)
4. Add subscripts (if necessary) so the charge for the entire compound is zero.
5. Use the crisscross method to check your work.
Notes:

– Don’t write the subscript ‘1’.
– If you use the criss-cross method and end up with something like Ca2S2 you’ll need to reduce the subscripts to Ca1S1 which we write CaS.
Note: It is possible to have two polyatomic ions such as NH4NO3. In this case find and write both names as found on the Common Ion Table.
