Will this cause your calculated concentrations to be high
Suppose that there is something in your sample that is absorbing at the same wavelength as the material you are looking at. Will your measured %T be too high or too low? Will this cause your calculated concentrations to be too high or too low?

The electrical resistor transfers 95 Btu of energy into the system. Eventually the system comes to equilibrium. Determine the final equilibrium temperature, in °F.
The shark tank at an aquarium houses 5 sharks that deplete theaquarium water of a total of 50.00 grams of oxygen per hour. Waterfrom the tank is diverted through a bubbler unit that oxygenatesthe water using a stream of oxygen-rich air, and then i
Hydrogen peroxide solutions are purchased from chemical suppliers at a 3.0% by mass concentration. Calculate the molar concentration of a 3.0% H2O2 solution, assuming a density of 1.0 g/mL.
What is the current fill rate (i.e., the fraction of demand met from inventory)? b. Assume that the lead-time is reduced to two weeks, while r and Q are unchanged. What is the fill rate?
A solution is made to be 3.8 * 10-2 M in Al3+ and .29 M in NaF. If the Kf for AlF63+ is 7 * 1019, how much aluminum ion remains at equilibrium?
A saturated solution of barium chloride at 30C contains 150 g water. How much additional barium chloride can be dissolved by heating this solution to 60C?
Calculate the heat losses associated with microbial degradation of carbofuran (in kJ), taking into account that both energy and biomass are produced, and that energy conversion to ATP is only 40% efficient (Eo'(CO2/carbofuran) = -0.38).
Explain why some molecules are best represendted by resonance structures, and how these structures indicate the actual structure of the molecule.
If the melting point of the compound is unknown the melting point measurement could take an exceedingly long time if the rate of heating of 2C/min is followed over the entire range from room temperature to the melting.
Consider the titration of 50.0 ml of a 0.100 M solution of the protonated form of alinine (H2A^+; Ka1 = 4.6 x 10^-3; Ka2 = 2.0 x10^-10) with 0.100 M NaOH. Calculate the ph after the addition of the following volume of base.
