Question

How many milliliters of a 0.900% (m/v) normal saline solution can be prepared from 3.50 g of sodium chloride, NaCl

Answer 1

Answer:

389 mL solution

Explanation:

Step 1: Given data

• Concentration of the NaCl solution: 0.900% (m/v)

• Mass of sodium chloride: 3.50 g

• Volume of saline solution: ?

Step 2: Calculate the volume of saline solution

The concentration of the NaCl solution is 0.900% (m/v), that is, there are 0.900 g of NaCl every 100 mL of solution.

3.50 g NaCl × 100 mL solution/0.900 g NaCl = 389 mL solution
