CHM-101: Fundamentals of Chemistry

CHM-101 is SNHU's introductory chemistry course, built around the role chemistry plays in everyday life.

SNHU's catalog says the course lets students look at the world around them through the lens of chemistry, introducing basic concepts and applications along with chemical topics and their relationship to matters of societal concern.

A separate 1-credit lab, CHM-101L, uses laboratory techniques to study principles such as the mole, chemical equilibria, chemical and physical properties, solutions and kinetics.

Students without a science background often worry about the maths. The arithmetic is manageable; the bigger step is learning to think about matter at the level of atoms and molecules.

What CHM-101 Covers

Exact module topics vary by term, so follow your course outline for what is assessed.

Key Concepts Explained

The Mole

Atoms are far too small to count, so chemists count them in moles. One mole contains about 6.022 x 10²³ particles, and the molar mass in grams equals the formula mass from the periodic table.

Physical Versus Chemical Change

Melting ice changes state but not identity; it is physical. Burning wood produces new substances (carbon dioxide, water, ash); it is chemical. Many everyday-chemistry questions start by deciding which kind of change is happening.

Concentration

Concentration describes how much solute is in a given amount of solution. It explains why dose matters: the same substance can be harmless or harmful depending on how concentrated it is, a common theme when chemistry meets health and environmental issues.

Typical Assignments and How to Approach Them

Writing About Chemistry and Society

Because SNHU frames CHM-101 around everyday life and societal concern, some assignments ask you to explain the chemistry behind a public issue. Good answers do three things: describe the chemistry accurately in plain language, use reliable sources for any data, and separate scientific evidence from opinion.

For instance, writing about lead in drinking water means explaining how lead dissolves from old pipes, why acidity matters and what treatment does, before discussing policy. Accuracy first, argument second.

Writing CHM-101L Lab Reports

The companion lab covers the mole, equilibria, chemical and physical properties, solutions and kinetics. Most lab reports follow a familiar shape: purpose, materials and method, results, discussion and conclusion. Check your lab manual for the exact sections required.

In results, present data in clearly labeled tables with units. In discussion, compare your results with expected values, explain specific sources of error (a misread volume, heat loss, an impure sample) and say how each might have changed the outcome. A short, honest discussion beats a long, vague one.

Where Students Get Stuck

• Unit errors. Most wrong answers come from dropped or mixed units.
• Unbalanced equations. Count atoms of each element on both sides before calculating.
• Memorizing without understanding. Ask what is happening to the particles.
• Weak sources. Use textbooks, government agencies and peer-reviewed work for applied papers.

Study Tips for CHM-101

• Keep a periodic table beside you for every problem set.
• Rework examples from your readings before trying new problems.
• Explain one concept aloud each week as if to a friend.
• Link each topic to something in your kitchen, car or bathroom cabinet.

How We Help with CHM-101

Send the problem set, lab instructions and data, the rubric and any feedback. A chemistry tutor can prepare step-by-step worked solutions, explain concepts or review your lab report for structure and accuracy. Our lab report writing guide covers the standard sections.
