Example: How many moles of oxygen atoms are there in 0.723 moles of aluminum nitrate, Al(NO3​)3​?(6.51 moles) 12.) Know how to predict the daughter nucleus in a nuclear equation. Example: What is the other product in the alpha decay of 235U ?(23Th) 13.) Know how to use half-lives of a radioactive substance to determine time for activity to decrease a given amount. Example: A specific isotope has a half-life of 15 minutes. How long will it take for the activity of this isotope to decrease from 32 millicuries to 8.0 millicuries?(30. minutes) 14.) Know the groups in the periodic table (Alkali metals, alkaline earth metals, halogens, noble gases). Example: Which of these is a halogen? Al, F,Na,Ca,Ne(F) 15.) Know how to calculate molarity. Example: A solution is prepared by dissolving 14.23 grams of KCl in enough water to make 1,245 mL of solution. What is the molarity of the KCl in this solution?(0.1533 M) 16.) Know how to find the molarity of an ion in a solution. Example: What is the molarity of C2​H3​O2​−in a 0.519M solution of Sr(C2​H3​O2​)2​ ?(1.04 M) 17.) Know how to use the dilution equation. Example: How many mL of a 1.45M solution of sucrose should be diluted to a final volume of 275 mL so that the resulting solution is 0.223M in sucrose?(42.3 mL) 18.) Know how to use mass/volume percent ( m/v% ). Example: How many grams of glucose are required to make 1.75 L of a 4.54%( m/v) solution of glucose? (79.5 g)
