Question

Qual o volume, em litros, que existem em 4400 g de CO2? Dados: MC = 12u; MO = 16u a) 10 b) 100 c) 1000 d) 10000

Answer 1

$\small\boxed{\begin{array}{l}\underline {\sf C\acute alculo\,da\,massa}\\\rm M_{CO_2}=12+2\cdot16=12+32=44\,u\\\rm 44~u\longrightarrow22,4\,L\\\rm 4400\longrightarrow x\,L\\\rm 44x=22,4\cdot4400\\\rm x=\dfrac{22,4\cdot\diagup\!\!\!\!\!4\diagup\!\!\!\!\!4\diagup\!\!\!0\diagup\!\!\!0^{100}}{\diagup\!\!\!\!4\diagup\!\!\!\!4}\\\\\rm x=22,4\cdot100\\\rm x=2240~L \end{array}}$
