Explore how measurements combine a number with a unit, why the international system of units standardizes science, and how prefixes create practical derived units.
Master dimensional analysis and unit conversion techniques using metric prefixes, convert between centimeters, meters, and nanometers, and solve practical problems involving volume, density, and apothecary and troy weight units.
30+ Questions to practice for this topic
Explore the three fundamental chemical laws: conservation of mass, definite proportions, and multiple proportions. See how mass is conserved, compounds have fixed element ratios, and ratios are whole numbers.
Learn to name ionic compounds by identifying the cation and anion, using -ide endings for monoatomic ions, and applying polyatomic ions such as nitrate and ammonium, balancing charges.
Main problem set with solutions for atomic history and periodic table of elements topic.
30+ Questions to practice problems associated with atomic structure, history, and elements, as well as naming compounds practice
Explore isotopes, elements with the same atomic number but different numbers of neutrons, such as hydrogen and carbon isotopes, and distinguish mass number from atomic mass.
Learn Avogadro's number and the mole, converting atomic mass units to grams, and using molar mass to find how many grams correspond to a given number of particles.
Apply mole calculations from Avogadro's number to convert between atoms, moles, and mass, with practice problems on iron, carbon, diamond, and chloral hydrate.
You're probably finding this page because you're worried about taking the AP exam. Perhaps your frustrated with the existing online resources available, or maybe you're having a difficult time keeping up in class. Contrary to popular belief, the chemistry exam is actually quite easy to do well in, and this course will provide you with the steps and tools to succeed on test day.
Hello everyone!
My name is Sunny and I've been a professional Chemistry tutor for the past 4 years. As a 5-scorer on the AP Chemistry Exam myself, I've invested over 800 hours in tutoring dozens of students for their AP chemistry courses/exam. In 2019 I started RhomiTutoring, which provides online 1-on-1 tutoring to students around the world. By far the most requested subject amongst my students was chemistry, and particularly Collegeboard's Advanced Placement Chemistry. The combination of mathematics, problem solving, and memorization of the contest can make it daunting for many students.
At present, there are many educational videos you can find on the subject but few are structured in such a way that follows a detailed curriculum, and the vast majority don't provide practice problems to students, or the practice problems are simply not at the level of difficulty that would be needed to achieve a 5.
That's why this course was designed to have an emphasis on problem sets. It contains 6 broad topics, with each topic containing quizzes, lectures and 40+ exercises, along with 10+ hours of lectures and 12 problem sets.
1. Mathematical Foundation for Chemistry
2. Chemical History and Elements
3. Stoichiometry
4. Kinetics and Thermodynamics
5. Equilibrium
6. Acids and Bases
