A) 1010 M

C) 10.1 M
D) 1.01 M
E) 0.101 M

Question

Quizplus · Accepted Answer

Molarity is defined as moles of solute per liter of solution. Since the molecular weight of chloride (Cl-) is not given, it's assumed that the given concentration in mmol/L directly translates to molarity (M) because mmol/L is equivalent to mM (millimolar), which is 0.001 M. Therefore, 101 mmol/L is 0.101 M.
