Give your chemistry students a focused look at grams to moles conversion with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.

Sample questions include "How many moles are in 160 grams of ethanol (C₂H₅OH)?", "Convert 60 grams of potassium hydroxide (KOH) to moles?", and "Convert 250 grams of sulfuric acid (H₂SO₄) to moles?"

What's Inside?

• 30 Multiple Choice questions as a separate print ready PDF worksheet
• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
