FIU CHM 1045: General Chemistry I

CHM 1045 (with the CHM 1045L lab) is FIU's first general chemistry course — measurement, stoichiometry, atomic structure, periodicity, bonding, and gases — serving the university's large pre-health, biology, and engineering populations. Note the number: FIU uses CHM 1045 where some other Florida schools number the same course 2045.

Fennie is independent and not affiliated with Florida International University. This is an unofficial study guide.

What makes it hard

Stoichiometry is the gating skill, and the course is merciless about it: students still slow at mole conversions after the first month spend the rest of the term underwater, because every later chapter assumes that fluency. Exams are timed and calculation-dense, and the separate lab adds pre-labs and reports that make chemistry cost more weekly hours than its credit count admits.

What you'll cover

  • • Measurement and dimensional analysis
  • • Stoichiometry and the mole
  • • Atomic structure and periodic trends
  • • Chemical bonding and Lewis structures
  • • Molecular geometry
  • • Gas laws

The CHM 1045 study guide

How to study for FIU CHM 1045, step by step.

  1. 1

    Make mole math reflexive within three weeks

    Stoichiometry gates everything after it in CHM 1045. Short daily conversion drills until grams-to-moles-to-particles is automatic — fluency here is the cheapest insurance in the course.

  2. 2

    Front-load the pure memorization

    Polyatomic ions, nomenclature, solubility basics — into flashcards in the first weeks. Exam time should go to multi-step reasoning, not to recalling what sulfate is.

  3. 3

    Practice under a clock from the first exam on

    Timed, calculation-dense exams punish slow accuracy as much as error. Weekly timed problem sets train the speed the format demands.

  4. 4

    Budget the lab as its own course

    CHM 1045L's pre-labs and reports have their own deadlines and their own grade. Plan the week assuming chemistry takes half again the hours the credit count suggests.

How Fennie helps with CHM 1045

Fennie's Daily Plans drill CHM 1045's gating skills daily until mole math is automatic, then pace exam review around lab-report deadlines so neither buries the other. Auto-generate flashcards from your notes for the memorization layer, and chat through missed multi-step problems to find exactly which step failed.

FAQ

Is CHM 1045 a weed-out class at FIU?

It functions as one for pre-health and science tracks — timed calculation-heavy exams, cumulative skills, and a separate lab workload. It's reliably passable with weekly problem volume and early stoichiometry fluency; it reliably punishes note-rereaders.

Is FIU's CHM 1045 the same as CHM 2045 at other Florida schools?

Functionally yes — it's the same first general chemistry course in the statewide numbering system, and it transfers as such. FIU simply catalogs it at the 1000 level, so don't panic when the numbers don't match a friend's schedule at another state school.

Do I take CHM 1045L at the same time as CHM 1045?

Most FIU degree maps pair them, and downstream courses expect both completed. The lab is a separate grade with pre-labs and reports on their own schedule, so treat it as additional weekly workload, not an afterthought.

More FIU courses

COP 2210 — Programming I

COP 2210 is FIU's first programming course, taught in Java — objects and classes, control flow, methods, arrays, strings, and file I/O. It's a 4-credit course with a required closed instructional lab, and it's the front door of the FIU computing majors, feeding directly into COP 3337.

COP 3337 — Programming II

COP 3337 is FIU's second programming course, deepening Java: inheritance, polymorphism, interfaces, exception handling, recursion, and an introduction to data structures. It's the bridge between writing programs that work and writing programs designed well, and it's a prerequisite for COP 3530 and CDA 3102.

COP 3530 — Data Structures

COP 3530 covers data organization and algorithm analysis — running time, abstract data types, linked lists, trees, sets, graphs, and sorting. It's the gateway to FIU's upper-division CS curriculum, and fittingly, the canonical data structures textbooks by Mark Allen Weiss were written by an FIU professor.

CDA 3102 — Computer Architecture

CDA 3102 covers the levels of organization in a computer: digital logic, machine and assembly language programming, and the design of memory, buses, the ALU, and the CPU, with virtual memory and I/O at the end. It's where FIU CS students find out what their Java has been running on all along.
