The most perilous incident, the World War IV has just been fought between the Angels and Demons. The Demons, tried their best to annihilate the Angels by firing a deadly poisonous gas on them.

The Angels, too, wanted to stop the catastrophe. Thus they started finding more about the gas. On their chary scrutiny, the gas was found to be 1.1×108 kg1.1\times10^{8}\text{ kg} of phosgene.

They created a counter-gas, each molecule of which could stop the effect of each molecule of phosgene.

How many molecules of the counter-gas do the Angels need to prevent the demise of their fellow mates?
