Question: Isotope
Answer: Atoms of the same element with different numbers of neutrons
Question: Atomic Mass
Answer: An amu is defined as exactly 1/12 of a carbon-12 atom
Question: Average Atomic Mass
Answer: The average atomic mass is a combination of the two or more naturally occurring
isotopes, it is the weighted average of their atomic masses.
Question: Avogadro's Number
Answer: 6.022 x 10^23 Symbol is NA
Question: Mole
Answer: A mole is the number of carbon-12 atoms in exactly 12 grams of carbon-12. Symbol is
n.
Question: Mass to Mole
Answer: n=m/M
Question: Molar Volume
Answer: 1 mil of any gas at STP has a volume of 22.7L. n=v/vstp
Question: Number of Particles to Mole
Answer: n=N/Na
Question: Particles
Answer: The particles could be atoms for an element, molecules for a molecular compound, or
formula units for an ionic conjoined.
Question: Qualitative Analysis
Answer: Carried out to identify the composition of a substance or a mixture. The focus is on
determining which chemical species are present in the sample.
Question: Quantitative Analysis
Answer: Involves identifying the quantity of each species in a sample.
Question: Mole Ratio
Answer: Every mole ratio is derived from a balanced chemical equation and shows the relative
amounts of the species in moles. Wanted over Given.
