The conversion factor stands at 760 mmHg/atm.
3.1 atm * 760 mmHg/atm = 2356 mmHg
An individual likely came into contact with the chemicals and sustained an injury.
To determine the molarity of a solution, you take the amount of solute in moles and divide it by the solution's volume. For NH4Br, its molar mass is known to be 98. Consequently, the molarity can be calculated as follows: (14/98) mol / 0.15 L = 0.95 mol/L.
Answer:
The molar concentration of Fe³⁺ in the unknown solution is 8.01x10⁻⁵M.
Explanation:
When creating a calibration curve in spectrophotometric analysis, you apply Lambert-Beer’s law, which indicates that the absorbance of a compound is directly related to its concentration:
A = E*l*C
Where A stands for absorbance, E is the molar absorption coefficient, l is the path length, and C represents the molar concentration
Using the line equation, you find:
y = 4541.6X + 0.0461
Where Y is the absorbance and X refers to the concentration - we will presume the concentration is expressed in molarity-
Given that the absorbance of the unknown is 0.410:
0.410 = 4541.6X + 0.0461
X = 8.01x10⁻⁵M
The molar concentration of Fe³⁺ in the unknown solution is 8.01x10⁻⁵M.
