Answer:
-0.6⁰c
Explanation:
find the solution below
a. 4.12 x 10-5 M
b. 7.09 x 10-3 M
c. 4.12 x 10-2 M
d. 2.41 M
To find the molarity of the solution, we need to use the formula:
Molarity (M) = moles of solute / volume of solution (in liters)
First, let's calculate the number of moles of NaCl using its molar mass (MM):
Mass of NaCl = 1.00 gram
Molar mass of NaCl = 58.5 g/mol
Moles of NaCl = Mass of NaCl / Molar mass of NaCl
= 1.00 g / 58.5 g/mol
≈ 0.0171 mol
Next, we need to convert the volume of the solution from milliliters (mL) to liters (L):
Volume of solution = 415 mL = 415 / 1000 L
= 0.415 L
Now, we can calculate the molarity:
Molarity (M) = moles of solute / volume of solution
= 0.0171 mol / 0.415 L
≈ 0.0412 M
Therefore, the molarity of the solution is approximately 0.0412 M.
The closest answer option is c. 4.12 x 10^-2 M.
