The temperature of a chemical reaction was found to be $353\mathrm{.}2K.$ what is the temperature in $F,C$ and $R?$

In smokehouse processing of a material, a final temperature of $155F$ inside the material is often used. Calculate this temperature in $C,K$ and $R$

Air is assumed to be composed of $21$mol$\%$ oxygen and $79$mol$\%$ nitrogen. Calculate the average molecular weight of air.

The gas $CO$ is being oxidized by $O_2$ to form $C{O}_2.$

a$.$ How many $kg$ of $C{O}_2$ will be formed from $56kg$ of $CO?$

b$.$ Calculate the $kg$ of $O_2$ theoretically needed for this reaction.

A gaseous mixture contains $20g$ of $N_2,83g$ of $O_2,$ and $45g$ of $C{O}_2.$ Calculate:

a$.$ The composition in mole fraction

b$.$ The average molecular weight of the mixture.

A liquid solution contains $1\mathrm{.}15wt\%$ of a protein, $0\mathrm{.}27wt\%$ of $KCl,$ and the remainder water. The average molecular weight of the protein by gel permeation is $525000g$ mass $\frac{?}{g}$ mol. Calculate the mole fraction of each component in solution.
