Review I Constants I Periodic Table

An empty $3\mathrm{.}65L$ steel vessel is filled with $1\mathrm{.}95$atm of $C{H}_4(g)$ and $7\mathrm{.}80$atm of $O_2(g)$ at $300C.$ A spark causes the $C{H}_4$ to burn completely, according to the equation:

$C{H}_4(g)+2O_2(g)C{O}_2(g)+2H_{2}O(g)H$

Part A

What mass of $C{O}_2(g)$ is produced in the reaction?

$m_{C{O}_2}=6\mathrm{.}66g$

Previous Answers

Correct

Correct answer is shown. Your answer $6\mathrm{.}65g$ was either rounded differently or used a different number of significant figures than required for this part.

Part B

What is the final temperature inside the vessel after combustion, assuming that the steel vessel has a mass of $12\mathrm{.}990kg,$ the mixture of gases has an average molar heat capacity of $21\frac{J}{\text{m}\text{o}\text{l}*C},$ and the heat capacity of steel is $0\mathrm{.}499\frac{J}{g*C}?$
