We know that concentration is typically expressed with molarity, which is moles per liter. But how do we know how many moles of solute are present in solution when an ionic solid dissolves in water? It's not so simple because these will...

In this video, the teacher explains how to use knowledge of converting measurements to solve real-life volume problems.

Measure liquid volume using units of liter.

We know how to express solution concentration in terms of molarity and molality, but the common public also needs to communicate concentration for certain reasons, and they don't really know about moles and things like that. What do they...

This is a educational video about solving word problems involving mass and volume using addition and subtraction. The video discusses the units of mass and volume, operation word clues, and common misunderstandings about numbers. The...

In this live-action program viewers will learn that the SI is an international system of standardized measurement used by scientists worldwide. Students will come to understand that the SI is made up of a list of base units defined by...

Now those pesky moles are swimming! But how much solute is there? Let's learn about how we measure concentrations of solutions.

This program introduces students to the usefulness and fun of the metric system. The concept of measurement as related to the metric system kicks off the video, followed by examples of how the metric system is used in science. Through a...

In this video, the teacher explains how to solve multiplication and division word problems about volume by drawing pictures. The example given involves calculating the amount of coffee each person receives when bringing five boxes of...

In this educational video, the teacher explains the concept of volume and demonstrates how to calculate the volume of different three-dimensional shapes such as cubes, cuboids, and cylinders. The teacher also shows how to find the volume...

This video provides an introduction to the metric system and its importance in scientific communication. It explains the history of the metric system, its base unit of measurement (the meter), and how larger and smaller measurements are...

In this video, students learn about volume and how it is measured using the metric system. The video also introduces the units of liters, milliliters, and cubic centimeters, and demonstrates their use in measuring volume. This video is...
