Depends on where you live but generally speaking it is either June or July

Hydrogen gas(H2) has a molar mass of 2 g. Molar mass of a substance is defined as the mass of 1 mole of that substance. And by 1 mole it is meant a collection of 6.022*10^23 particles of that substance.
So number of moles of H2 are 0.5 in this case. And thus it means there are (6.022*10^23)*0.5 particles( here they are molecules) in 1g of H2.
That would be lactic acid fermentation. When the body is low on oxygen, and has a high amount of NADH, the pyruvate from glycolysis is fermented into L-lactate.
