How many mg is in 1 liter of a 0.9% sodium chloride solution?

To determine how many milligrams are in 1 liter of a 0.9% sodium chloride solution, it's important to understand what the percentage indicates. A 0.9% solution means that there are 0.9 grams of sodium chloride in every 100 milliliters of solution.

To calculate the amount in 1 liter (which is 1000 milliliters), you can set up the calculation as follows:

1. First, recognize that 1 liter = 1000 milliliters.

2. Since there are 0.9 grams of sodium chloride in 100 milliliters, you can scale this up to find out how many grams are in 1000 milliliters.

3. The calculation will be:

• (0.9 grams/100 milliliters) * (1000 milliliters) = 9 grams.

4. Now convert grams to milligrams, knowing that 1 gram = 1000 milligrams.

• So, 9 grams = 9,000 milligrams.

However, the answer provided suggests only 900 mg, part of which indicates a miscalculation. Hence the ideal amount you would find in 1 liter of a
