Note that a particle is an atom, molecule, or formula unit.ĥ.44 x 10 26 atoms Co x 1 mole = 904 molesĢ.4 moles CO 2 x 6.02 x 10 23 molecules = 1.4 x 10 24 moleculesġ9. Use Unit Analysis to Change from particles to moles or from moles to particles. State Avogadro's # three different ways describing the number of atoms in a mole, formula units in a mole, and molecules in a mole. Use unitĪnalysis! Start the unitanalysis with 17.865 h and end with atoms H.ġ7.865 h x 3600 s x 1.5 coulomb x 6.24 x 10 18 e x 1 atom H = 6.02 x 10 23 atoms Hġ6. Period of 17.865 hours, calculate Avogadro’s number (the number of atoms in 1.00g of hydrogen).

If 1.00 g of hydrogen is generated at a current of 1.50 amps (1 amp = 1 coulomb per second) and over time An amp meter is used to measure the rate of electron For every 1 electronĬonsumed 1 atom of hydrogen (exact) is generated. Mole Calculations to Molecular Formula 6ĭescribe each particle as an atom, molecule or a formula unit.ġ5 The electrolysis of water using H 2SO 4 as a catalyst is used to generate hydrogen gas. Percentage Composition Empirical Formula 5Ħ. Moles of gasoline: How many moles of gasoline are in a gallon or liter of gasoline? How much do you pay per mole? Your students can do these calculations, while you rest easy with a complete answer key.Grams and Moles Homework: Convert grams to moles… you get the idea.Grams and Moles Calculations: Convert grams to moles.Moles-Molecules-Grams Worksheet: Pretty much what it sounds like.Mole Calculations I (dd-ch): More grams-moles-molecules fun.Mole Calculations Worksheet: More moles than you can shake a stick at!.Molar Masses III (dd-ch): Why is this called “Molar Masses III” when this is the second sheet? It’s one of the mysteries of life.Molar Mass Worksheet: If your students need practice finding molar masses, you’re in the right place!.Good for those of you who don’t find the Conversion Commandments handout amusing. Rules for Performing Unit Conversions: The same as above, except it’s not written in “Ten Commandments” form.The Conversion Commandments: A handout to help your students figure out if their answers make sense.
