DynamicHW: One & Two Step Molar Conversions

One and Two-step molar conversions calculator and 12 question worksheet generator. Change your worksheet 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)

Calculator (sheet labeled 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).

DynamicHW (sheet labeled 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 and you'll have your own worksheet and answer key, just like the preview file.

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