Molecular oxygen is produced by the decomposition of kclo3. how many liters of o2 are produced by the complete decomposition of 100.0 g of kclo3 at stp?

27.5 liters

Explanation:

To calculate the moles, we use the equation:

For

Given mass = 100.0 g

Molar mass of   = 122.5 g/mol

Putting values in above equation, we get:

2 moles of produces 3 moles of

0.82 moles of produces = moles of

Volume of

Thus 27.5 liters of are produced by the complete decomposition of 100.0 g of at STP

im not exactly sure but i think its b!

i do not get it   at all
