Question

what mass of KCL O3 in gram should be heated to produce 11.2 litres of O2 gas at NTP? explain numerically please​

Answer 1

Heya!!

_____________________________________________________________✨✨

Balance the equation

2KCLO3 ____> 2KCL + 3O2

i.e

to get 3 mole of O2 , 2 mole of kClo3 required.

also, 3 mole of O2 = (3×22.4)L oxygen

= 67.2L oxygen

so,

to get 67.2 L oxygen 2 mole of KClO3 required.

so,

to get 11.2 L of 02 .... (2/67.2 )×11.2 = 0.33 mole of KCLO3 required.

molecular mass of kClO3 = 122.5g

i.e 1 mole of KCl03 = 122.5g

0.33 mole = (0.33× 122.5)g

hope it helps!!
