Your Element in Moles
	Exemplary 3 pts	Acceptable 2 pts	Unacceptable 1 pts
AMUs (#2, #3) 1 amu is approximately the mass of one proton or one neutron.	Exemplary You know the atomic mass of your element, and can manipulate it.	Acceptable You know the atomic mass of your element.	Unacceptable You do not know the atomic mass of your element.
Moles (#1, #5) 1 mole contains 6.022x10^23 representative particles	Exemplary You know how many particles are in one mole, and understand the concept of a "representative particle."	Acceptable You know how many particles are in one mole.	Unacceptable You do not know how many particles are in one mole.
Molar mass (#4, #6) g/mol 1 gram contains 6.022x10^23 amus	Exemplary You are able to identify that the molar mass of your element is dependent on the atomic mass, and are able to find the molar mass in a sample problem.	Acceptable You are able to identify that the molar mass of your element is dependent on the atomic mass, but unable to find the molar mass in a sample problem.	Unacceptable You are unable to identify that the molar mass of your element is dependent on the atomic mass, and unable to find the molar mass in a sample problem.
Using molar conversion factors (#7) g-->mol	Exemplary You are able to take the mass in grams of your element and divide it by the molar mass to find moles.	Acceptable You are able to (with help) take the mass in grams of your element and divide it by the molar mass to find moles.	Unacceptable You are unable to take the mass in grams of your element and divide it by the molar mass to find moles.
