Accepted Answer

***D*** ∻Key Concept∻ ⚹Avogadro's number and mole concept⚹ ∻Explanation∻ ⚹Sample D has $6.0 imes 10^{23}$ H atoms, which is Avogadro's number, representing one mole of H atoms, the largest finite number of H atoms among the options. To find the smallest number, we need to convert all samples to the number of H atoms and compare. Sample B, with $1 imes 10^{-9}$ mg of $\mathrm{H}_2$, will have the smallest number of H atoms because it is a minuscule mass compared to the other samples.⚹◊Which sample contains the greatest number of hydrogen (H) atoms according to the provided information in the chemistry problem?⍭ Generate me a similar question◊
