Our host describes ways to express solution concentration. The class learns about mass percent and the students propose plans for creating solutions with a known molarity. Obtain, evaluate, and ...
Researchers can use a metric called the particle number concentration (PNC) to calculate the number of particles in a sample, such as the number of marbles in a jar. Researchers at the National ...
The host introduces solutions, acids and bases and their importance in chemistry. The students begin a lab, adding different salts to water at different temperatures and observing the conditions under ...
