Breanne needed to find the percent composition of the compound KClOz The percent of potassium in the compound yes approximately A) 29% 32% 39% 43% Hydrogen peronde is a harmful by product of normal metabolic activity. In order to prevent damage, b, drogen peroxide mus: be​

Respuesta :

The percent of potassium in the compound KClO₃ = 32%

Further explanation

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison, so that compounds have a fixed composition of elements

[tex]\tt \%mass=\dfrac{Ar~element\times number~of~element~in~compound}{MW~compound}\times 100\%[/tex]

We determine the molecular mass of KClO₃ then we determine the Ar from K (potassium) and the amount in the compound

MW KClO₃ : 122,55 g/mol

The amount of K in KClO₃ = 1

So %K :

[tex]\tt =\dfrac{39}{122,55}\times 100\%=31.8\%\approx 32\%[/tex]
