What is the molar mass of calcium bromide?

Answer 1

#"199.89 g/mol"#

Determining the chemical formula of a compound is the first step towards determining its molar mass.

The chemical formula of calcium bromide is #"CaBr"_2# because calcium has a #2+# charge and bromine has a #1-# charge, so you need two bromide anions to cancel out calcium's charge.

Next you have to locate the two elements on the periodic table and record their molar masses. Add calcium's mass plus bromine's #xx2# because you need to multiply times the amount of atoms of an element there are.

This is how the equation looks:

#"40.078 g/mol" + 2 xx ("79.904 g/mol") = "199.89 g/mol"#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
