Oxygen is prepared by catalytic decomposition of potassium chlorine `(KClO_(3))`. Decomposition of potassium, chloride gives potassium chloride (KCl) and oxygen `(O_(2))`. How many moles and how many grams of `KClO_(3)` are required to produce 2.4 mole `O_(2)`?

A

2

B

3

C

1.6

D

1.5

Text Solution

Verified by Experts

The correct Answer is:
C
3 moles of `O_(2)` are formed by 2 moles of `KClO_(3)`
2.4 moles of `O_(2)` will be formed by
`2/3xx2.4` = 1.6 moles of `KClO_(3)`.
