What is the molar mass of Au(CN)2

249.01 g/mol

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

Au(CN)₂

Step 2: Identify

Molar Mass of Au - 196.97 g/mol

Molar Mass of C - 12.01 g/mol

Molar Mass of N - 14.01 g/mol

Step 3: Find MM

Molar Mass of Au(CN)₂ - 196.97 + 2(12.01) + 2(14.01) = 249.01 g/mol

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

ill try to . no promises tho.
