A common solution used by EMTs for keeping VEINS from collapsing in accident victims is 5% (m/v) dextrose (C6H12O6) in water. Write a recipe to make 450 ml (One blood unit) Of 5% (m/v) dextrose in water.
To make 450 ml (One blood unit) of 5% (m/v) dextrose in water, follow these steps:
1. Weigh out 22.5 grams (0.0225 kg) of dextrose (C6H12O6) using a digital scale.
2. Place the dextrose into a large beaker or flask.
3. Add about 200 ml of distilled water to the beaker and stir until the dextrose is completely dissolved.
4. Once dissolved, add enough distilled water to the solution to make a total volume of 450 ml.
5. Stir the solution again to ensure the dextrose is evenly dispersed, resulting in a final concentration of 5% (m/v) dextrose in water.
6. Finally, transfer the solution to a sterilized container, preferably a IV bag, for use by EMTs in emergency situations.
To make 450 ml of a 5% (m/v) dextrose solution in water, follow the recipe below:
Ingredients:
- Dextrose (C6H12O6) powder
- Distilled water
Instructions:
1. Calculate the amount of dextrose powder needed:
- 5% of 450 ml is equal to (5/100) * 450 ml = 22.5 grams of dextrose.
2. Bring a clean container with a capacity larger than 450 ml.
3. Measure and weigh 22.5 grams of dextrose powder.
4. Add the measured dextrose powder to the container.
5. Pour distilled water into the container up to the 450 ml mark.
6. Close the container tightly and make sure it is properly sealed.
7. Shake the container vigorously until the dextrose powder is completely dissolved in the water.
8. Ensure that no undissolved particles of dextrose remain in the solution.
9. The 450 ml solution of 5% (m/v) dextrose in water is now ready for use. Label the container appropriately for identification.
Note: It is important to follow safety guidelines and use proper lab practices when working with chemicals and solutions.
