Problem

An intravenous (IV) infusion bag contains

0.900\,\text{L}

of a sterile

0.90\,\%\,(m/v)

NaCl solution (i.e.,

0.90\,\text{g NaCl}

per

100\,\text{mL}

of solution). During patient treatment the solution is delivered at a constant rate of

35.0\,\text{mL min}^{-1}

. Respond to the prompts below. Show complete calculations and clearly state final answers with units. (1) Part 1: a) Calculate the total mass of NaCl (in grams) initially present in the IV bag. (2) Part 2: b) Determine the total number of

Na^+

ions present in the full bag before infusion begins. (3) Part 3: c) Compute the number of

Na^+

ions that enter the patient’s bloodstream during a 25.0-min infusion period. (4) Part 4: d) If a physician orders that the patient receive

1.20\times10^{22}

Na^+

ions, for how many minutes must the infusion run? Assume the flow rate remains constant and the concentration of the solution does not change appreciably during the infusion.
