Question

Quantos gramas de cloreto de hidrogênio gasoso são formados a partir de 142 gramas de cloro gasoso?

Answer 1

$\Large\boxed{\begin{array}{l}\underline{\rm Equac_{\!\!,}\tilde ao\,balanceada}\\\sf HCl\longrightarrow H+CL\\\underline{\boldsymbol{C\acute alculo\,das\,massas\,molares\!:}}\\\sf HCl=1+35,5=36,5~g/mol\\\sf Cl=35,5\,g/mol\\\sf 36,5\,g\,de\,HCl\longrightarrow35,5\,g\,de\,Cl\\\sf x\longrightarrow 142\,g\,de\,Cl\\\sf 35,5x=152\cdot36,5\\\sf x=\dfrac{5548}{35,5}\\\\\sf x=156,28\,g\,de\,HCl\end{array}}$
