Solution: 12/6.022*10^23 = 1.9927*10^-23. We know that carbon 12 has a mass of 12 a.m.u and 1 amu =1.66*10^-24 grams.
Hydrogen has an atomic mass of 1.01 atomic mass units. An atomic mass unitis TINY. One gram is equal to about 600000000000000000000000 amu (or 6followed by 23 zeros). So, because the mass of hydrogen is close to 1 amu,1 gram of hydrogen contains about that same huge number of atoms.
