____ is the concentration, in milligrams per milliliter, of a solution containing 23.5 mEq of sodium chloride per milliliter. Round answer to the nearest whole number. Do not include units. (MW of NaCl is 58.5)

Step 1 is to identify the formula to convert milliequivalents (mEq) to milligrams (mg) Formula: mg = (mEq × MW) ÷ valence Valence of NaCl (Sodium Chloride) = 1 MW = 58.5 Step 2 is to calculate the milligrams per milliliter (mg/mL) mg = (23.5 × 58.5) ÷ 1 23.5 × 58.5 = 1374.75 (1374.75 ÷ 1) = 1374.75 Result at this step = 1374.75 mg/mL Step 3 is to round to the nearest whole number 1374.75 ≈ 1375 Answer: 1375
