Final answer:
To find out how many grams of sodium chloride are in a 25 mL solution with a 0.16 M concentration, we use the molar mass of NaCl and the volume in liters. .45 Normal Saline Sodium Chloride Contraindications include hyperchloremia and hypochloremia, which may be aggravated with inappropriate administration of saline solutions.
Step-by-step explanation:
The .45 Normal Saline Sodium Chloride Contraindications question is related to the concentration of sodium chloride (NaCl) solutions, particularly when used in medical contexts such as IV (intravenous) solutions or isotonic solutions for contact lenses that match the physiological saline concentration of the human body, which is approximately 0.16 M.
To calculate the mass of sodium chloride in a 25 mL solution at a concentration of 0.16 M, we can use the formula:
mass (g) = volume (L) × concentration (M) × molar mass (g/mol). The molar mass of NaCl is approximately 58.44 g/mol, hence for 0.025 L (25 mL): mass = 0.025 L × 0.16 M × 58.44 g/mol.
Regarding contraindications, too much NaCl can lead to hyperchloremia while too little can lead to hypochloremia. It is important to be aware of contraindications such as pre-existing heart failure, kidney issues, or electrolyte imbalances which could be exacerbated by sodium chloride administration.
