(1 point) Convert the following absorbances into percent transmittance values: 0.100 b) 0.500
2. Convert a percent transmittance reading of 58.1% into absorbance. (Refer to pages 11 and 65 of the lab manual). 3. Will the boiling point of a liquid be higher or lower than its boiling point at standard atmospheric pressure (760 mm Hg) if it is boiled at a lower atmospheric pressure? (Refer to page 66 in the lab manual)
If you use a Spec-20 with an analog scale you must read percent transmittance, and convert your transmittance reading to absorbance. What is the absorbance of a solution that transmits 100% of the light shining on it? What is the absorbance of a solution that transmits 5.0% of the light? What is the absorbance of a solution that transmits 0% of the light shining on it?

Sometimes a person will read the percent transmittance scale of a colorimeter rather than the absorbance scale and then convert %T into "A." What value of "A" corresponds to each of the following: 10% T, 50% T, 90% T ?
Consider the titration of 100.0 mL of 0.100 M methylamine (CH3NH2) with 0.500 M HNO3. Calculate the pH at the following volumes of acid added. For CH3NH3+, pKa = 10.632 (a) Find the equivalence point volume. (b) 0 mL (c) 9.0 mL (d) 10.0 mL (e) 20.0 mL (f) 30.0 mL
PROBLEMS 1) Acids and bases: Calculate the following a) [H30] in a 0.500 M solution of HCl b) pH of a 0.100 M solution of HCI c) pH of a 0.100 M solution of HNO3 d) [OH] in a 0.500 M solution of HClnote, for this you need to use Kw e) pH of a 0.100 solution of NaOH (also need to use some form of Kw here)
1. A volume of ___ mL of 0.100 M NaOH(aq) is required to titrate 0.500 g of potassium hydrogen phthalate (often abbreviated KHP) to the endpoint. 2. A 0.5741 g sample of a monoprotic acid was titrated with 0.1008 M NaOH(aq). If 37.89 mL of sodium hydroxide solution were required for the titration, the molar mass of the monoprotic acid is ___ g/mol.
Consider mixture B, which will cause the net reaction to proceed forward. Concentration (M)initial:change:equilibrium:[XY]0.500?x0.500?xnet??[X]0.100+x0.100+x+[Y]0.100+x0.100+x The change in concentration, x, is negative for the reactants because they are consumed and positive for the products because they are produced. Based on a Kc value of 0.250 and the given data table, what are the equilibrium concentrations of XY, X, and Y, respectively?
