In the compound PtCl2(NH3)2, what is the percentage of the mass due to nitrogen?

(mass N)/mass compound)*100 =??

To find the percentage of the mass due to nitrogen in the compound PtCl2(NH3)2, we need to calculate the molar mass of the compound and determine how much of the total mass is contributed by nitrogen.

Here's how we can do it step by step:

Step 1: Determine the molar mass of PtCl2(NH3)2
- The molar mass of platinum (Pt) is 195.08 g/mol.
- The molar mass of chlorine (Cl) is 35.45 g/mol.
- The molar mass of nitrogen (N) is 14.01 g/mol.
- The molar mass of hydrogen (H) is 1.01 g/mol.
- Since there are two chloride ions (Cl) in the compound, we multiply the molar mass of chlorine by 2.

Let's calculate the molar mass of the compound:
Molar mass of PtCl2(NH3)2 = (195.08 g/mol) + (2 × 35.45 g/mol) + (2 × (2 × 1.01 g/mol)) + (2 × (2 × 14.01 g/mol))

Step 2: Calculate the mass of nitrogen
- The molecular formula of ammonia is NH3, which means it contains one nitrogen atom.
- In PtCl2(NH3)2, there are two ammonia ligands, so the total number of nitrogen atoms is 2.

Let's calculate the mass of nitrogen:
Mass of nitrogen = (2 × 14.01 g/mol) × (1 mol/6.022 × 10^23 molecules) × (1 molecule/1 atom)

Step 3: Calculate the percentage of the mass due to nitrogen
- The compound PtCl2(NH3)2 contains various elements, but we are interested in the nitrogen contribution, so we need to determine what portion of the total molar mass is due to nitrogen.

Let's calculate the percentage of the mass due to nitrogen:
Percentage of mass due to nitrogen = (mass of nitrogen / molar mass of PtCl2(NH3)2) × 100

By following these steps and plugging in the values, you can find the percentage of the mass due to nitrogen in the compound PtCl2(NH3)2.
