Answer: 0.502mol Explanation: The balanced chemical equation of the reaction described in this question is as follows: 2KClO3 → 2KCl+ 3O2 According to the equation above, 2 moles of KClO3 will produce 2 moles of KCl. Using mole = mass/molar mass to convert mass of KClO3 to moles Molar mass of KClO3 = 39 + 35.5 + 16(3) = 39 + 35.5 + 48 = 122.5g/mol mole = 61.5 g ÷ 122.5g/mol mole = 0.502mol Since 2 moles of KClO3 will decompose to produce 2 moles of KCl. 0.502 mol of KClO3 will decompose to produce 0.502 × 2/2 = 0.502mol of KCl.

Answer:
0.502mol
Explanation:
The balanced chemical equation of the reaction described in this question is as follows:
2KClO3 → 2KCl+ 3O2
According to the equation above, 2 moles of KClO3 will produce 2 moles of KCl.
Using mole = mass/molar mass to convert mass of KClO3 to moles
Molar mass of KClO3 = 39 + 35.5 + 16(3)
= 39 + 35.5 + 48
= 122.5g/mol
mole = 61.5 g ÷ 122.5g/mol
mole = 0.502mol
Since 2 moles of KClO3 will decompose to produce 2 moles of KCl.
0.502 mol of KClO3 will decompose to produce 0.502 × 2/2
= 0.502mol of KCl.
