What volume of oxygen gas is produced when 17.5 grams of KBrO3 decomposes?

and the equation is KBrO3==>KBr+30

HELP ME PLZ

1 answer

Where did you get that reaction equation? Atomic O is not stable product

The reaction is actually
2 KBrO3 -> 2 KBr + 3 O2

Calculate the number of KBrO3 moles you start with, using the molar mass; then take 3/2 that number as the number of moles of O2 that form. Call it n.

The use V = n R T/P for the volume V

You need to specify the absolute temperature T and pressure P. At 0 C and 1 atm, each mole occupies 22.4 liters.

I'll be glad to critique your work.
