What is the molarity of 750 mL of NaCl solution that contains 21.04 g of NaCl?
The Periodic Table
A. 0.028 mol/L
B. 0.48 mol/L
C. 28 mol/L
D. 4.8 x 10-4 mol/L

volume of solution = 750 mL = 0.750 L

mass of solute = 21.04 g

solute: NaCl

molarity

Step 1: Calculate the molar mass of solute.

molar mass of solute = (22.99 g/mol × 1) + (35.45 g/mol × 1)

molar mass of solute = 58.44 g/mol

Step 2: Calculate the number of moles of solute.

moles of solute = mass of solute / molar mass of solute

moles of solute = 21.04 g / 58.44 g/mol

moles of solute = 0.360027 mol

Step 3: Calculate the molarity.

molarity = moles of solute / volume of solution

molarity = 0.360027 mol / 0.750 L

molarity = 0.48 mol/L

B. 0.48 mol/L

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
