Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

Calculate the molar mass and the centesimal composition of chemical substances with this interactive calculator.

Determining empirical formula from analytical data, and determing molecular formula from empirical formula, with flow charts and sample calculations.

In this activity, students use the virtual lab to prepare a sucrose solution for a soda recipe. They next calculate the concentration of their solution in terms of molarity, percent mass and density. Finally, they compare the density of...

Students use a Conductivity Probe to measure change in conductivity during a chemical reaction and determine the equivalence point of the reaction They determine the mass of the product and calculate the molar concentration of the...
