CHM 101 Exam 3 Fall 2021 Potentially useful information: 1 inch = 2.54 cm (exactly) 1 lb = 453.6 g 1 quart = 0.9464 L 1 mL = 1 cm3 1 m = 109 nm (or 10-9 m = 1 nm) 760 mmHg = 760 torr = 1 atm 109 nm = 1 m 1 Cal = 1000 cal = 1 kcal 4.184 J = 1 cal Avogadro’s Number: 6.022 × 1023 E = hν (h = 6.626 × 10–34 J∙s) hc E= λ moles solute Molarity = L solution Activity Series c = λν (c = 3.00 × 108 m/s) M1V1=M2V2 At a given temperature and pressure, equal volumes of gases contain equal numbers of moles (gas particles). Different gases at the same temperature have the same average kinetic energy. P1V1 = P2V2 q = mC∆T (where q is heat, m is mass, C is specific heat, and ∆T is change in temperature) Formulas of some common polyatomic ions: NO3–, HCO3–, CO32–, SO42–, PO43–, NH4+ All compounds containing any of the following are soluble: Na+, K+, Li+, NH4+, NO3–, CH3CO2–
