Final answer:
The resultant percentage concentration of codeine phosphate when 30 grams is dissolved in 2 liters of solution is approximately 1.477%.
Step-by-step explanation:
To calculate the percentage concentration of a solution when 30 grams of codeine phosphate is dissolved in 2 liters of solution, we use the formula:
Percentage Concentration = (mass of solute / mass of solution) × 100%
First, we need to convert liters of solution to grams. Assuming that the density of the solution is similar to water, 2 liters would have a mass of approximately 2000 grams (since the density of water is about 1 gram per milliliter).
Next, we add the mass of the codeine phosphate to the mass of water:
- Mass of water = 2000 grams
- Mass of codeine phosphate = 30 grams
- Total mass of the solution = 2030 grams
Now, we can insert the values into the formula:
Percentage Concentration = (30g / 2030g) × 100% = 1.477% (rounded to three decimal places)
The resultant percentage concentration of codeine phosphate in the solution is approximately 1.477%.
