A sample gives (A = 0.45) in a 1 cm cuvette, (\varepsilon = 9000 \ \textM^-1\textcm^-1). Find (c).

If 0.25 g of NaOH (M = 40.00 g/mol) is dissolved in 250 mL of water, what is the molarity? Introduction to Contextual Maths in Chemistry .pdf

Equilibrium: [N₂] = 0.1 – (x), [H₂] = 0.3 – 3(x), [NH₃] = 2(x). Then (K_c = \frac(2x)^2(0.1-x)(0.3-3x)^3). Solve for (x) (approximation if (K_c) small). 3.4 Thermodynamics Gibbs free energy: [ \Delta G = \Delta H - T\Delta S ] A sample gives (A = 0
