Americium is a radioactive element .
- It goes through alpha decay during nuclear reactions .
The nuclear reaction.is given by
- Np stands for Nuptunium
Here alpha can be written as He too
To solve this problem, let us all convert the mass of each element into number of moles using the formula:
moles = mass / molar mass
Where,
molar mass K = 39.10 g / mol
<span>molar mass Cl = 35.45 g / mol</span>
molar mass O = 16 g / mol
<span>and mass O = 13 g – 4.15 g – 3.76 g = 5.09 g</span>
moles K = 4.15 g / (39.10 g / mol) = 0.106 mol
<span>moles Cl = 3.76 g / (35.45 g / mol) = 0.106 mol</span>
moles O = 5.09 g / (16 g / mol) = 0.318 mol
The ratio becomes:
0.106 K: 0.106 Cl: 0.318 O
We divide all numbers with the smallest number, in this case 0.106. This becomes:
K: Cl: 3O
Therefore the empirical formula is:
