An aqueous solution contains 38.6 g NaCI per 155 mL of solution. This solution is _________.
WHAT? clear? colorless? priceless? poison?
Molarity
moles NaCl = grams/molar mass
M = moles/0.155L = ??
To determine what type of solution the given aqueous solution is, you need to calculate its concentration in terms of grams per liter (g/L).
First, calculate the concentration of NaCl in grams per milliliter (g/mL). Given that the solution contains 38.6 g NaCl per 155 mL, divide the mass of NaCl by the volume of the solution:
Concentration of NaCl (g/mL) = 38.6 g / 155 mL
Next, convert the concentration from g/mL to g/L. There are 1000 mL in a liter, so multiply the concentration by 1000:
Concentration of NaCl (g/L) = (38.6 g / 155 mL) * 1000 mL/L
Now, calculate the final concentration of NaCl in the solution in g/L:
Concentration of NaCl (g/L) = (38.6 g / 155 mL) * 1000 mL/L = 249.032 g/L
The aqueous solution contains 249.032 g NaCl per liter of solution.
Based on the concentration, we can determine the type of solution. Since the concentration is greater than 200 g/L, the solution is considered a saturated solution.
