Question

If 0.5 moles of hydrogen gas are produced how many molecules of hydrogen gas was made

Answer 1

We can use the relation between moles and number of molecules to find out how many hydrogen gas molecules (H2) were produced:

`1\text{ mole = 6}*10^(23)\text{ molecules}`

In this case, 0.5 moles of H2 were produced, so we can set the following proportion:

`\begin{gathered} 1\text{ mole-----6}*10^(23)\text{ molecules} \\ 0.5\text{ moles----x molecules} \\ \\ x=(6*10^(23)*0.5)/(1)=3*10^(23)\text{ molecules } \end{gathered}`

So, we have produced 3x10^23 molecules of hydrogen gas.

`\begin{gathered} (600)/(2)=300 \\ (6*10^2)/(2)=3*10^2=300 \end{gathered}`
