The best fit curve line to an absorbance vs. concentration plot for standard solutions of a dye has a slope of 0.1815 ml/mg and intercept of 0.0477. a sample solution prepared of the same dye has an absorbance of 0.464 at the wavelength used to establish the beer's law plot. what is the concentration of dye in the prepared solution? select one:

Which statement describes the appearance of a temperature-vs.-time graph? a horizontal line shows that the temperature increases at a constant rate over time. a vertical line shows that the temperature decreases at a constant rate over time. horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases. horizontal lines where the temperature increases are connected by upward-sloping lines where the temperature is constant for each phase.

Which atom or ion is the largest? a. k b. k+ c. ca d. ca2+ e. li
