Percentage Composition and Empirical & Molecular Formula

In this compounds activity, high schoolers review the structure and properties of ionic compounds, their formulas and nomenclature, and molecular mass and percentage composition. This activity has 4 short answer questions and 7 problems...

In this molecular mass and percent composition worksheet, learners complete 5 sections where they determine atomic masses of given elements, they determine formula masses for given molecules, they find the molecular mass of 12 molecules...

Nine action-packed organic chemistry exercises are contained in this mini-unit on carbon containing compounds. Examples include constructing models of alkanes, producing aromatic esters, and preparing pigments for paint and dyes....

In this molecular mass and percent composition worksheet, students find the molecular mass of 10 compounds to three decimal places. They also find the percent composition of 7 compounds and express their answers to two decimal places.

After giving the definitions of the different compound terms and formulas, equations are provided to teach your chemists to calculate different values. Relative formula mass, atomic mass, and empirical mass are shown and explained with...

Practice naming chemical compounds or stating the formula when given the name. Discover how well you have mastered these skills either by time or percentage correct.

Relative molecular masses sure have a lot of decimal places! Watch the video to learn how the number of particles in one mole of carbon-12 determines relative atomic and molecular masses. Viewers also learn how to calculate the atomic...

What's the formula for success? A unique and well-written resource from JFR Science explains empirical and molecular formulas. Young chemists learn the steps and skills required to determine the formulas from percent composition and...

Students of chemistry are shown how to calculate the empirical formula from a molecule's mass composition. Sal uses a variety of elements from the Periodic Table to demonstrate the process and the calculations involved to arrive at the...

Video tutorial presents different ways of representing a molecule and gives examples to demonstrate the difference between empirical, structural, and molecular formulas. [6:49]
