What is the molarity of a solution containing 29.2 grams of NaCl in 0.60 liters of solution?
MM(NaCl) = 58.4 g/mol

Question

Quizplus · Accepted Answer

Molarity = moles of solute / liters of solution

First, we need to calculate the moles of NaCl:

moles of NaCl = mass / molar mass
moles of NaCl = 29.2 g / 58.4 g/mol
moles of NaCl = 0.5 mol

Now that we know the moles of NaCl, we can calculate the molarity:

molarity = moles of solute / liters of solution
molarity = 0.5 mol / 0.60 L
molarity = 0.833 M

Therefore, the answer is B, 0.833 M.
