What mass of caco3 (in grams) is needed to make 10.5 l of a 1.50 m caco3 solution?
kiruha [24]
Data:

M = 1.50 (assiming the data is Molarity and not molality, which is written with capital letter)

V= 10.5 l

n = ?

Formulas:

M = n / V => n = M * V

n = mass in grams / molar mass => mass in grams = n * molar mass

Solution

n = 1.50 * 10. 5 l = 15.75 moles

molar mass CaCO3 = 40.08 g/mol + 12.01 g/mol + 3* 16 g/mol = 100.09 g/mol

mass in grams = 15.75 moles * 100.09 g/mol = 1,576.4 g.

Answer: 1,576 g

Describe how you would prepare a supersaturated solution.
mestny [16]
First, heat the solute to a high temperature, but not boiling. Next, dissolve the solute into the heated solution until the solute will no longer dissolve. Once that happens, take the heated solution off the heat and allow it to cool. Once the solution is cool you now have a supersaturated solution.
