Answer:
The answer to your question is Pd₂H₄
Explanation:
Data
mass of palladium = 42.56 g
mass of hydrogen = 0.8 g
Process
1.- Convert the grams of each substance to moles
106 g of Pd ----------------- 1 mol
42.56 g of Pd ------------- x
x = (42.56 x 1)/106
x = 0.402 moles
1 g of H --------------------- 1 mol
0.8 g of H ------------------ x
x = (0.8 x 1)/1
x = 0.8 moles
2.- Divide by the lowest number of moles
Palladium = 0.402/0.402 = 1
Hydrogen = 0.8/0.402 = 1.99 ≈ 2
3.- Write the empirical formula
PdH₂
4.- Calculate the mass of the empirical formula
PdH₂ = 106 + 2 = 108
5.- Divide the molar mass by the molar mass of the empirical formula
216.8/108 = 2
6.- Get the molecular formula
2(PdH₂) = Pd₂H₄
