Question

If 2.5 ggiven off? of KCLO3 were heated in a test tube, how many grams of oxygen gas should be

Answer 1

1.46878825 g O_3

Step-by-step explanation:

the balanced equation is:

2 KClO_3 = 2 KCl + 3 O_2

using stoichiometry, you can find the amount of O_2 produced from 2.5 g KClO_3

2.5 g KClO_3 x (1 mol / 122.55 g KClO_3) x (3 mol O_3 / 2 mol KClO_3) x (48 g O_3 / 1 mol O_3) = 1.46878825 g O_3
