Determine o volume de gás oxigênio (O2) ocupado por 3x1096 moléculas desse gás.

Answer 1

$\boxed{\begin{array}{l}\underline{\rm observe~os~dados~a~respeito~do~composto~O_2\!:}\\\sf1~mol~de~mol\acute eculas\\\sf6\cdot10^{23}mol\acute eculas\\\sf2~mols~de~\acute atomos\\\sf2\cdot6\cdot10^{23}\acute atomos\\\sf32~g\\\sf22,4~L. \\\sf note~que~a~2^a~e~6^a~informac_{\!\!,} \tilde oes\\\sf nos~ajuda~a~solucionar~a~quest\tilde ao. \end{array}}$

$\boxed{\begin{array}{l}\sf assim,\\\sf 6\cdot10^{23}~mol\acute eculas\longrightarrow22,4~L\\\sf3\cdot10^{96}~mol\acute eculas\longrightarrow x\\\sf x=\dfrac{22,4\cdot\diagdown\!\!\!3^1\cdot10^{96}}{\diagdown\!\!\!6_2\cdot10^{23}}\\\sf x=\dfrac{\diagdown\!\!\!\!\!\!22,4\cdot10^{96}}{\diagdown\!\!\!2\cdot10^{23}}\\\sf x=11,2\cdot10^{96-23}\\\sf x=11,2\cdot10^{73}\\\sf x=1,12\cdot10^{74}~L\end{array}}$
