QUESTION: Problem 68P
Calculate each of the following quantities:
(a) Grams of solute in 185.8 mL of 0.267 Mcalcium acetate
(b) Molarity of 500. mL of solution containing 21.1 g of potassium iodide
(c) Moles of solute in 145.6 L of 0.850 M sodium cyanide
ANSWER:
Step 1 of 5
(a)
Given data:
The volume of sodium acetate solution: 185.8 mL = 0.185 L.
The molarity of sodium acetate: 0.267 M
To calculate: Mass of solute
The number of moles of solute can be calculated by using the following formula:
Where,
n = number of moles of solute
c = concentration of the solution
v = volume of the solution
By plugging the values in equation 1, we get:
The molar mass of sodium acetate = 82.034 g/mol
