The number of molecules in 16 grams of oxygen gas is 3.01*10^23, equal to half of Avogadro's number. One mole of oxygen gas is approximately 32 grams. Sixteen grams of oxygen gas is half a mole.
Continue ReadingAvogadro's number is 6.02*10^23 atoms or molecules per mole. One mole of oxygen is 16 grams, so one mole of oxygen gas is 32 grams.
If one mole of oxygen gas is 32 grams, then 16 grams is equal to half a mole of oxygen gas. The number of molecules in half a mole is equal to half of Avogadro's number. Sixteen grams of oxygen gas contains 3.01*10^23 molecules.

Full Answer >The oxidation number of oxygen in H_{2}O_{2} is -1. The state of oxidization directly corresponds to the change in the number of electrons when one atom joins other atoms in a compound.
Full Answer >There are 1.67 sextillion H_{2}O molecules in a drop of water. This is determined by using the formula of 50 microliters per drop of water.
Full Answer >N2O, or nitrous oxide, has many Lewis dot structures since both nitrogen and oxygen can act as the center atom. In total, there are three valid Lewis dot structures for nitrous oxide.
