Answer the following. If there is a calculation, clearly show each part, please:
a. Define the solute, probable solvent, and solution in this problem.
b. Which 3 main types of calculations are needed to solve this problem?
c. Why do % by mass and ppm reference the mass of the solution, rather than the solvent?
d. Calculate the % by mass (g/g) for Na2CO3 in this solution.
e. Calculate the ppm for Na2CO3 in this solution.
f. In this problem, which unit (% by mass or ppm) is more convenient to express the amount of Na2CO3 in the solution?
g. Calculate the M for Na+ in this solution.
h. Calculate the M for CO3^2- in this solution.
i. What is the total concentration of ions in this solution? (Add up the concentrations of each species.)
