Question

Help with Chemistry!! Will give medals. Posting problem in next post. Please help ASAP

Answer 1

find mole ratio , multiply the mole ratio of CS2 with avogadro's no. and by unity method u can find the amount

Answer 2

First, find the moles 16 kg of CCl4 are equal to, then use the stoichiometric coefficients to find moles produced. Set up a ratio using the species of interest, like so:

e.g. for a general reaction:

\(\color{red}{a}A + \color{blue}{b}B\) \(\rightleftharpoons\) \( \color{green}{c}C\)

where upper case are the species (A,B,C), and lower case (a,b,c) are the coefficients ,

\(\dfrac{n_A}{\color{red}{a}}=\dfrac{n_B}{\color{blue}{b}}=\dfrac{n_C}{\color{green}{c}}\)

From here you can isolate what you need.
For example: if you have 2 moles of B, how many moles of C can you produce?

solve algebraically: \(\dfrac{2}{\color{blue}{b}}=\dfrac{n_C}{\color{green}{c}}\rightarrow n_C=\dfrac{2*\color{green}{c}}{\color{blue}{b}}\)
--------------------------------------------------------
then i guess they're asking you for mass, convert the moles of CS2 to mass.
