David Sang and Graham Jones Solutions for Chapter: Ideal Gases, Exercise 3: Questions

The mass of one atom of carbon-$12$ is $12\mathrm{u}$. Determine the mass of one atom of carbon-$12$ in kg, given that $1\mathrm{u}=1.66\times {10}^{-27} \mathrm{kg}$.

The mass of one atom of carbon-$12$ is $12\mathrm{u}$. Determine the number of atoms and the number of moles in $54 \mathrm{g}$ of carbon.

The mass of one atom of carbon-$12$ is $12\mathrm{u}$. Determine the number of atoms in $1.0 \mathrm{kg}$ of carbon.

Calculate the mass in grams of a single atom of uranium- $235$ of mass $235\mathrm{u}$.

A small pellet of uranium-$235$ has a mass of $20\mathrm{mg}$. For this pellet, calculate the number of uranium atoms.

A small pellet of uranium-$235$ has a mass of $20\mathrm{mg}$. For this pellet, calculate the number of moles.

It can be useful to recall that $1.0 \mathrm{kg}$ of ordinary matter contains in the order of ${10}^{26}$ atoms. Making suitable estimates, test this statement.
