General Formulas and Concepts:

Chemistry - Atomic Structure

Reading a Periodic Table
Using Dimensional Analysis

Explanation:

Step 1: Define

54.2 g N

Step 2: Identify Conversions

Molar Mass of N - 14.01 g/mol

Step 3: Convert

$54.2 \ g \ N(\frac{1 \ mol \ N}{14.01 \ g \ N} )$ = 3.86867 mol N

Step 4: Check

We are given 3 sig figs. Follow sig fig rules and round.

Suppose a platinum atom in the oxidation state formed a complex with two chloride anions and two ammonia molecules. Write the ch

Blababa [14]

Answer: Pt(Cl)2(NH3)2

Explanation:

In the formation of the complex, the oxidation number of platinum is plus two (+2) and two chloride ions cancel it out by their oxidation number of -1 each. Hence the complex has an overall charge of zero. It is thus neutral with no charge attached to its formula.
