Dilutions

Young scholars determine the molar volume of hydrogen gas. In this molar volume lesson plan, students find the molar volume of hydrogen produced in a reaction between magnesium and hydrochloric acid. They use a eudiometer to measure the...

Chemistry pros calculate mass, volume, concentration, or molarity of five different solutions. This tidy activity makes an appropriate homework assignment when studying molarity.

The Earth is over 70% water and so are our bodies. What makes water so special? Learn about water and its properties as it relates to solutions, dilutions, electrolytes, and molarity.

Why are chemists great for solving problems? They have all the solutions. Introduce your young chemists to the various ways of describing solutions, including molarity, molality, and mass percent, with a video that also explains why...

Students find the standard molar volume of a gas. In this molar volume of a gas lesson plan, students react magnesium metal and hydrochloric acid and collect the hydrogen gas produced using a gas collection tube. Students calculate the...

Calculating molar volume from experimental data often means the additional challenge of complex numbers and slight errors in measurement. The 23rd video in a 30-part series offers two types of experimental data to work from and models...

In the United States, motor vehicles cause around 75 percent of the carbon monoxide pollution, but how do we measure this pollution? The 21st video in a series of 30 discusses what we mean by molar volumes of gases. It...

Scientists require specific chemical solutions for their experiments. In the seventh and final installment in a series that integrates chemistry and algebra II, scholars learn to set up a system of equations to solve the volume of a...

When no more solute can be dissolved into a solvent, the solution has reached saturation. The interactive simulation allows learners to manipulate a solution in order to measure its concentration. The amount of solvent, the amount and...
