CHEM 117: Introductory Chemistry

This instructional video demonstrates the process of calculating the mass percent of various solutions, using the formula "mass of solute divided by mass of solution, all multiplied by 100%." It provides step-by-step calculations for three different solutions, revealing the concentration of each solute in terms of mass percent, offering a practical understanding of quantifying solute proportions in solutions.

Discover Lewis structures for various molecular formulas, including N2, HCN, CO2, C3H6, and more. Explore their chemical bonding and structural arrangements.

Explore the chemical combination of nitrogen and fluorine to produce nitrogen trifluoride. Learn how to determine the limiting reactant and calculate the theoretical yield using stoichiometry principles.

In this problem, we are tasked with determining the pressure of neon gas in a 0.75-L cylinder at 30°C after compressing it from a 2.50-L sample at 0.00°C and 1.00 atm using the combined gas law equation, with step-by-step calculations leading to a final pressure value of approximately 3.699 atm.

Discover how to determine the density of mineral oil and a metal ball bearing using a graduated cylinder. Learn the method of calculating the mass difference and volume to deduce the density and radius of the ball. Watch a detailed physics experiment explained step by step.
