QUESTION 40 YOU MUST SUBMIT WORK FOR THIS PROBLEM INTO A SEPARATE ASSIGNMENT. A sample of KCIO3 with unknown mass has been thermally decomposed according to the following equation: KCIO3 (s) 0 2 KCI (s) + 3 02 (g) Vhat was the mass of the KCIO3 sample (in grams) if a 6.72 L of the gas product of this reaction was collected at the temperature of 680.0°C and under the p Molar marcer (in a(mole): KCI0n = 122 55: KCL= 74 55: 0n = 32.00
