For You Determine the concentration of a solution made by dissolving 10.0 g of sodium chloride (NaCl) in 0.75 L of solution.
Reminder of the the steps:
1. Identify what you know and what you want, and the units.
Known: 0.75 L, 10.0 g NaCl
Want: molarity (mol/L )
2. Find the amount of NaCl in moles.
molar Mass of NaCl = 58.44 g/mol.
Formula: Moles = grams / molar mass
3. Use dimensional analysis to set up and solve equation.
Formula: M = mol solute /L solution
Select one:
O a. 0.133 M
b. 0.171 M
c. 0.228 M
d. 0.476 M
