How do you determine the formula and molar mass of silver cyanide?
You must identify the type of bond(s) present. In this case, it is an ionic compound.
You must also identify the elements/polyatomic ions present. In this case, there is silver (
- If there was a multivalent element, you have to look at the chemical name. If there are Roman numerals, then the preceding element is multivalent with a charge of whatever the numerals indicate. E.g.
Knowing that it is an ionic compound, we know that the electrons are transferred. Thus the cation goes first (
You need a periodic table for this. The molar mass of a compound is simply the sum of all elements in the compound (including the subscripts if any; no coefficients if any).
Add them all up and you get
Hope this helps :)
