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

The percent of potassium in the compound KClO₃ = 32%

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

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 :

the answer is minerals.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
