(a)
Interpretation:
The concentration of species in ppm should be calculated.
Concept Introduction:
Concentration typically relates an amount of solute and the volume of solution. When relating small amounts, we typically use the unit ppm, which measures the number of units of solute per million units of solution. The best way to perform this calculation is to change solute amounts to milligrams and solution amount to kilograms.
This is best described as follows:
(b)

The concentration of species in ppm should be calculated.

- 6-91 When a cucumber is put into a saline solution to pickle it, the cucumber shrinks; when a prune is put into the same solution, the prune swells. Explain what happens in each case.arrow_forward6-55 According to the label on a piece of cheese, one serving of 28 g provides the following daily values: 2% of Fe, 6% of Ca, and 6% of vitamin A. The recommended daily allowance (RDA) of each of these nutrients are as follows: 15 mg Fe, 1200 mg Ca, and 0.800 mg vitamin A. Calculate the concentrations of each of these nutrients in the cheese in ppm.arrow_forward6-99 A concentrated nitric acid solution contains 35% HNO3. How would we prepare 300. mL of 4.5% solution?arrow_forward

How many kilograms of CI2 were added to the swimming pool to reach this concentration?arrow_forward6-82 (Chemical Connections 6C) A solution contains 54 mEq/L ofCI- and 12 mEq/L of HCO3-. If Na+ is the only cation present in the solution, what is the Na+ concentration in milliequivalents per liter?arrow_forward6-96 We know that a 0.89% saline (NaCI) solution is isotonic with blood. In a real-life emergency, you run out of physiological saline solution and have only KCI as a salt and distilled water. Would it be acceptable to make a 0.89% aqueous KCI solution and use it for intravenous infusion? Explain.arrow_forward
