Intro to dimensional analysis (video) | Khan Academy
Sal shows how we can treat units of measurement algebraically, and use these tools in order to convert between different units of the same quantity. Created by Sal Khan.
Conversion between metric units (video) | Khan Academy
Want to learn how to convert between different units of volume using prefixes like kilo, hecto, deka, deci, centi, and milli? In this video, you'll see how to use these prefixes to compare …
Using units to solve problems: Drug dosage - Khan Academy
It's called dimensional analysis. If you ever get confused with these things-- and I think, once you do enough practice, you'll find that you won't have to pay too much attention to this.
Stoichiometry: mass-to-mass and limiting reagent - Khan Academy
Learn to convert between the masses of reactants and products using balanced equations and molar masses. Additionally, learn how to determine the limiting reactant to accurately predict …
Stoichiometry and empirical formulae (article) | Khan Academy
There are, however, tools common to all types of stoichiometry, which are dimensional analysis, Avogadro’s number, and molecular weight. Dimensional analysis allows conversion from unit …
Stoichiometry: mole-to-mole and percent yield - Khan Academy
Discover how to use balanced chemical equations to convert between moles of reactants and products, and calculate percent yield by comparing actual and theoretical yields.
Calculations using Avogadro's number (part 2) - Khan Academy
The aim of converting by using dimensional analysis is to convert an initial unit to a final, desired unit using a series of conversion factors. Each step of the process is us asking ourselves, …
