Work Problem: Calculation of Molar Mass of Unknown Base Using Titration With a Strong Acid

Given Question: A student titrates 2.0135 grams of an unknown monobase weak base to the equivalence point with 67.02 mL of .5003 M HCl(aq). What is the molar mass of the weak base?  Step 1: This is to sort out what we're given in the equation, as well as some previous knowledge. We'll use the first … Continue reading Work Problem: Calculation of Molar Mass of Unknown Base Using Titration With a Strong Acid

Determining the Density of a Face-Centered Aluminum Cell

Crystals come in unique shapes, but all usually have an organized, repeating structure known as a lattice. For more information about metal lattices check out: https://www.seas.upenn.edu/~chem101/sschem/metallicsolids.html  Given Problem: An aluminum crystal has a face-centered unit cell. An aluminum atom has a radius of 143 picometers. What is the density of the solid crystal aluminum in g/cm³?  … Continue reading Determining the Density of a Face-Centered Aluminum Cell
