Help your students build real understanding of composition quantity reasoning through ninety questions that move from basic recognition to genuine reasoning about chemistry concepts.
Sample questions include "How many grams of hydrogen are needed to produce 36 g of water?", "If you have 10 grams of Na and it reacts completely, how many grams of NaCl will be produced?", and "A compound with 40% carbon and a molar mass of 180 g/mol has how many grams of carbon?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a standards aligned chemistry unit. The unit also covers The Mole as a Counting Unit, Connecting Particles and Moles, Connecting Mass and Moles, Molar Reasoning in Quantitative, Stoichiometric Ratios, and Reaction Quantity Calculations, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 chemistry classes, and for review at any point in the school year. This set is aligned to Virginia SOL standard CH.4b.
