A series of solutions of known Nat content were used to prepare à calibration curve for flame emission analysis. Using data from the linear portion of the calibration curve gave slope = 0.125 emission units/ppm Na, and intercept or constant = 0.012. A 355-mL cane of juice was analyzed for its Na content by flame emission spectroscopy at the same time as the standard curve was determined. A 10.00-mL aliquot of juice was brought to a total volume of 100.00 mL with Na- free water. The diluted juice solution gave an emission intensity of 0.632 units. What was the Na ppm concentration in the cane of juice? If a person consumed the entire can of juice, how many mg Na+ would be ingested?

Question
A series of solutions of known Na+ content were used to prepare a calibration curve for flame emission analysis. Using data from the linear portion of the calibration curve gave slope = 0.125 emission units/ppm Na, and intercept or %3D constant = 0.012. A 355-mL cane of juice was analyzed for its Na content by flame emission spectroscopy at the same time as the standard curve was determined. A 10.00-mL aliquot of juice was brought to a total volume of 100.00 mL with Na- free water. The diluted juice solution gave an emission intensity of 0.632 units. What was the Na ppm concentration in the cane of juice? If a person consumed the entire can of juice, how many mg Na+ would be ingested?
