Question

When heated, KCIO, decomposes into KCl and O, 2 KCIO, 2 KCl +30, If this reaction produced 36.8 g KCl, how many grams of O, were produced? mass: 80

Answer 1

2 KO 2k1 + 302 mass of ked produced = 36.89. no. of mole of kee = may = 36.89 molar mas 74.5 g/mol = 0.494 mol Acc. to w 2 mol kce produe with 3 mole O2 then orgy mol kce prodhime with 0.494x3 = 0.741 modo, no. of mole of Oz produced = 0.74 med mass of or prodused = nxmolar mans = 0.741 molx 32 Ilmel = 23.79 Hence, 23.7g of Oq were produced.
