1st you need to find the mole ratio between KClO3 and O2. To find that you need to take the coefficents of each of the compounds. That gives a ratio of 2:3.
Now we find out how many each unit is:
2x = 12
x = 6
Now we multiply it by 3 to find the number of moles of O2
3(6) = 18 mol O2.
The final volume of the unknown gas is 787.5 ml
Given:
volume of unknown gas = 450.0 mL
initial pressure of unknown gas = 0.07 atm
final pressure of unknown gas = 0.04 atm
To Find:
final volume of the unknown gas
Solution:
Substituting these values into Boyle’s law, we get
P1V1 = P2V2
(0.07)(450) = (0.04)V2
V2 = (0.07)(450)/(0.04)
V2 = 787.5
So, final volume of the unknown gas is 787.5 ml

The neutrino is the particle that cannot be accelerated in a
magnetic field.
To add, a neutrino is a subatomic particle that is
very similar to an electron, but has no electrical charge and a very small
mass, which might even be zero.
