How to determine the empirical and molecular formula of a compound

Difference Between Osmosis And Diffusion

This problem discusses the main differences between osmosis and diffusion, as they are both passive transport mechanisms but differ in terms of how these processes occur.

Stoichiometry

We are given mass in grams of a particular compound. We need to convert it into moles of that compound given the ratio formula and the masses of individual elements.

finding average speed

In situations where you are given different speeds and the average speed is required, you need to keep in mind that the average speed is by definition: total distance/time elapsed. People get this wrong all the time, trying to do s= (s1+s2+s3+.. )/(number of s’s). Be careful.

Classic Mechanics Problem – Newton’s three laws of motion

Newton’s three laws of motion is the most frequent topic that you’ll definitely be tested in high school or college mechanics physics courses. The first law is the law of inertia, which means objects will stay in the current motion (static or dynamic) unless an unbalanced force F applied. Second law is the formula F…

Electricity and Magnetism

This is one of the most common concepts that will be tested on your physics exam. Whether it tells you to solve capacitance, resistance, current, or volts, you should know how to use the correct formula for each problem.

Kinematics Equations Problem

One of the most important and basic concepts in physics is Kinematics. You will need to understand all of its formula and which to use in different problem sets. Here is a random sample problem below.

Conservation of Kinetic and Potential Energy

Energy comes in many different forms. It can’t be created or destroyed, but it can move between objects and change forms. The energy of motion of a moving object is called kinetic energy, and is given by the equation KE = 0.5m(v^2) Where m is the object’s mass, and v is the object’s velocity. Another…

Converting between Metric Units

The Metric System is based on the fundamental units of measure for length, volume, and mass. Length: meter (m) Volume: liter (L) Mass : gram (g) Base units in the Metric System can be converted into units that are more appropriate for the quantity being measured by adding a prefix to the name of the…
