Calculate the molar concentration of a solution containing 33.8 grams of NaCl in 0.850 liters of water. The molar mass of NaCl is 58.44 g/mol.

0.680 M

Explanation:

Step 1: Given data

Step 2: Calculate the moles of NaCl (solute)

We will use the following expression.

n = m/M

n = 33.8 g/(58.44 g/mol) = 0.578 mol

Step 3: Calculate the molar concentration of NaCl

Molarity is the number of moles of solute divided by the liters of solution.

M = n/V = 0.578 mol/0.850 L = 0.680 M
