The right answer is high number of offspring produced. asexual reproduction only requires on orgainism and creates an identical copy leaving no room for an increase of intelligence. plus it creates much more offspring and more often than sexual reproduction.
Hydrogen + oxygen -> water
2H2 + O2 -> 2H2O (balanced)
2 moles of hydrogen gas will react with 1 mole of oxygen to produce 2 moles of water.
following that ratio, 0.734 mole of oxygen must need 0.734 × 2 moles of hydrogen to fully react.
answer is 1.468 moles of hydrogen.

contain =0.1 mol of sulphur atom.
Thus, number of sulphur-atoms =n×N

I would go with D on this one
