Answer:
4.90% is approximately the new Dextrose concentration.
Explanation:
Volume by Volume percent is given by ;
[tex](v/v)\%=\frac{\text{Volume of solute}}{\text{Volume of solution}}\times 100[/tex]
Volume percentage of dextrose solution = 5%
In 100 mL of solution 5 ml of dextrose is present.
Now, volume sterile water added was equal to the 40% of volume of dextrose volume.
So, volume of the sterile water added = [tex]\frac{40}{100}\times 5 ml = 2 mL[/tex]
Total volume of the solution after addition of water = 100 mL + 1 mL = 102 mL
New concentration of dextrose will be;
[tex](v/v)\%=\frac{\text{Volume of solute}}{\text{Volume of solution}}\times 100[/tex]
[tex]\frac{5 mL}{102 mL}\times 100=4.90\%[/tex]
4.90% is approximately the new Dextrose concentration.
