DynamicHW: Molar Conversions (ALL)

Get all three Molar Conversion DynamicHW Worksheet Generators at once; all three are in one Google Sheets file.

1. One Step Molar Conversions Calculator & DynamicHW Worksheet Generator
2. Two Step Molar Conversions Calculator & DynamicHW Worksheet Generator
3. Mixed Molar Conversions Calculator & DynamicHW Worksheet Generator

Each worksheet consists of 12 questions. Questions will use chemical formulas, as well as chemical names to encourage good nomenclature practice.

Change your worksheets every year. Produce multiple versions of the worksheet with varying numbers to prevent cheating or to give a student additional practice. This Google Sheet automatically generates an answer key for each version produced.

Have students work on molar conversions from...

One step

• mass (g) to moles
• moles to mass (g)
• particles (formula units, molecules, or atoms) to moles
• moles to particles (formula units, molecules, or atoms)
• gaseous volume (L) at STP to moles
• moles to gaseous volume (L) at STP

Two step

• mass (g) to moles to particles (formula units, molecules, or atoms)
• mass (g) to moles to gaseous volume (L) at STP
• particles (formula units, molecules, or atoms) to moles to mass (g)
• particles (formula units, molecules, or atoms) to moles to gaseous volume (L) at STP
• gaseous volume (L) at STP to moles to mass (g)
• gaseous volume (L) at STP to moles to particles (formula units, molecules, or atoms)

Calculators (sheets labeled One Step, Two Step, or Mixed): Fill-in the provided white boxes with a chemical formula or numeric value as labeled and watch the calculator solved the missing colored box. The dimensional analysis work will be shown to the right of the boxes.

The calculator could be used for the student that is struggling to do the work on his own. Repeatedly changing the white box values will help the student identify the pattern for the math work (dimensional analysis).

DynamicHWs (sheets labeled Worksheet (1 step), Worksheet (2 step), or Worksheet (mixed)): Fill-in the provided white boxes with a chemical formula or numeric value as labeled on the right of the sheet and watch the dynamic worksheet generate around row 45 of the sheet. Farther down the sheet, around row 135, the answer key with dimensional analysis work will be generated.

Print pages two through five on each of the worksheets and you'll have your own worksheets and answer keys, just like the preview file of the Mixed Worksheet.

NGSS: HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
