Question

How many moles of oxygen are formed when 58. 6 g of kno3 decomposes according to the following reaction? the molar mass of kno3 is 101. 11 g/mol.

Answer 1

Given the mass of KNO3 K N O 3 is 58.6 g and the molar mass is 101.11 g/mol. From the balanced equation, it is clear that for every 1 mole of KNO3 K N O 3 , 54 moles of oxygen is required. Therefore, 0.724 mol of oxygen is required for forming 58.6 g of KNO3 K N O 3 .
