Below are some objectives. Check if each objective possesses the SMART characteristics. If not, please suggest a revision for that objective. 1. know the meaning of atomic number and atomic mass 2. describe, on the molecular level, the effect of heating and cooling on the motion of molecules of a gas 3. identify different atoms 4. develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. 5. understand the formation of ions in ionic compounds

CHEM 120 Spring 2022 uquiz 3 February 7-10 1. Calculate the number of moles AND the mass in grams of a sample of Neon containing 2.790 X 1025 atoms of Neon. Note: this number of Ne atoms is NOT a number obtained by Name counting (i.e. you must consider the number of significant digits in this number for your final answer) Neon is 20.18 g/mol Avogadro's number 6.022 X 1023 You must show your work to receive credit. 20.18g/mol 6,.08M 10 49 2.790x10 6.022x 10* 1.68038x10
