5.3 Gas Stoichiometry

Daltons Law of Partial Pressure

• $P_t=P_1+...+P_m$
• Since in PV = nRT, in a fixed environment, ONLY the mol is changing, we can treat them like fixed variables
• $\to P_t=(n_1+...+n_m)\frac{RT}{V}$

Gas Vapour

• Use a table to match vapour pressure with temperature
• 
• Other than that, gas STOICH is pretty similar to unit 3, make sure to review that!!!

Some Calculative Tricks

Molecular Formula (shortcut)

Subscript of Element $=\frac{M_t\cdot \mathrm{\%}composition}{M\mathrm{element}}$
