Diffusion in one dimension
Because the definition of derivative is:
$\lim_{\Delta x\rightarrow0}\frac{f_{x+\Delta x}-f_x}{\Delta x}=\frac{\partial f}{\partial x}$
Applied to this case:
$\lim_{\Delta x\rightarrow0}\frac{N_{ix …

Chemical Engineering Process Analysis - Process Flow Calculations using linear matrices
Your question has issues. First you say "$\text{C}_{10}H_{14}$, $\text{C}_4\text{H}_6\text{O}_3$, and $\text{C}_{12}\text{H}_{16}\text{O}$ produced during a reaction", then you say "134 grams of $\tex …

Flow rate into a reactor from feed
Yes, weight percent of a component is the mass (flow rate) of that component divided by the total mass (total flow rate). Total flow rate is equal to the sum of the flowrates of every component.

Chemical engineering calculations - basis
As @user307640 said, if you use a mass basis, you can obtain the average molecular weight using the mass percentage composition.
As an alternative approach, you can do:
$\begin{align}
M&=\sum n_iMW_ …
