Question

Will kilogram of hydrogen contain more atoms than kilogram of lead? Explain.

Answer 1

Yes, because hydrogen atoms are smaller.

Answer 2

It takes more hydrogen atoms to equal one kilogram than lead atoms.

Answer 3

The molar mass of hydrogen is 1. Lead is higher.

Using mol concept, diving the mass by the molar mass gives you the number of mols, which is a measure of the amount of atoms.

So the same value of mass divided by a smaller value gives you a larger value, thus a kilogram of hydrogen will contain more atoms than a kilogram of lead.

Answer 4

\[\small1[\text{kg}]\text H=
1[\text{kg}]\text H\times10^3[\text g/\text{kg}]\div1.008[\text g/\text{mol}]\times6.022\times10^{23}[\text {atoms}/\text {mol}]\\
\quad\quad\quad=\dots\,\text H[\text {atoms}]\]

\[\small1[\text{kg}]\text{Pb}=
1[\text{kg}]\text{Pb}\times10^3[\text g/\text{kg}]\div207.2[\text g/\text{mol}]\times6.022\times10^{23}[\text {atoms}/\text {mol}]\\
\,\,\qquad\quad=\dots\,\text {Pb}[\text {atoms}]\]

Answer 5

A hydrogen atom is like 1 proton and a lead atom is like 26 protons and about as many neutrons. So basically if you were like made of magic you could literally break the iron apart into 26 hydrogen atoms.

Answer 6

Yes, @kainui gud explaination
