Convert 13.29 moles/L of NaCl to mg/mL.  Answer to 1 decimal place.  Exclude the units in your answer.MW(NaCl) =  58.44 g.mol-1

To convert the concentration from moles/L to mg/mL, we need to use the molar mass of NaCl, which is 58.44 g/mol.

Step 1: Convert the concentration from moles/L to g/L using the molar mass. 1 mole of NaCl = 58.44 g So, 13.29 moles/L = 13.29 moles/L * 58.44 g/mol = 776.2 g/L

Step 2: Convert the concentration from g/L to mg/L. 1 g = 1000 mg So, 776.2 g/L = 776.2 g/L * 1000 mg/g = 776200 mg/L

Step 3: Convert the concentration from mg/L to mg/mL. 1 L = 1000 mL So, 776200 mg/L = 776200 mg/L / 1000 mL/L = 776.2 mg/mL

So, 13.29 moles/L of NaCl is equivalent to 776.2 mg/mL. Rounded to one decimal place, this is 776.2 mg/mL.
