Based on the dissolved solute's properties, we can quantify that solute's concentration are too high to permit an accurate measurement. For example, a spectrophotometer can measure the amount of light that passes through a sample solution for If the solute's concentration is too high, a relatively small amount of incident light having the wavelength that corresponds to the solute's absorption behavior will less light is absorbed, and the detector in the spectrophotometer can generate more reliable data. reach the dete ctor, which results in an inaccurate measurement (consider the result if you blocked the light with an opaque…POin Elevation Aselution in preparnd by dissolving 15.60gof ordinary ger (sueroe, CHO, molecular weight-342 amu) in 15.00 gof water Calculante the boiling peier of the solution Sacose i anovolatile nonelectrolyte Solvent TC) THC) rCkg/mal) rChg/moll Benzene, Cal 80.1 253 55 530 Camphor, Cato 204 176 37.7 Cyciohexane, CH B0.88 2.79 6.50 202 Nitrobenzene, Cll, NO, 2108 524 81 water, H0 100.0 0.00 Submit Sho A h E Try A

- Question 5.d of 11 Submit Most anesthetic 'gases' are volatile liquids and therefore must be vaporized in order to be delivered in a gas form to the lungs. The vaporizer holds the gas in an equilibrium condition in which the concentration of the gas molecules remains constant on average. Oxygen gas then flows into the vaporizer and moves a mixture of O, and anesthesia into the tube for the patient. | %v/v 1 2 3 4 5 C 7 8 +/- x 10 0 Tap here or pull up for additional resourcesPrecipitimetry The chloride in a 4.321-g food sample was precipitated through the addition of 50.00 mL of a standard AgNO3 solution (10.00 mL AgNO3 = 11.22 mL KSCN).
