How do you calculate the concentration (ppm) if you have:
the amount of total solution (in ml)
the amount of sample that is added to the solution (in uL)
the density (g/mL)
See your post above to see my full response.
It would be so much easier to anwer if you posted the question with numbers instead of using a generic question.
Hi sorry! I'll post it.
How do you calculate the concentration (ppm) if you have:
the amount of total solution (60 ml)
the amount of sample that is added to the solution (15 uL)
the density (0.904 g/mL)
To calculate the concentration in parts per million (ppm) using the given information, you need to follow these steps:
Step 1: Convert the amount of total solution from milliliters (ml) to liters (L).
To convert ml to L, divide the amount of total solution by 1000 (1 liter = 1000 milliliters).
Step 2: Convert the amount of sample added to the solution from microliters (uL) to liters (L).
To convert uL to L, divide the amount of sample by 1,000,000 (1 liter = 1,000,000 microliters).
Step 3: Calculate the mass of the sample added to the solution by multiplying the density by the volume of the sample. The resulting unit will be in grams (g).
Step 4: Calculate the concentration in ppm by dividing the mass of the sample added (in grams) by the total volume of the solution (in liters), and then multiplying the result by 1,000,000.
Here is the formula for ppm concentration calculation:
ppm = (mass of the sample added / total volume of the solution) * 1,000,000
Please note that ppm (parts per million) is a weight-to-weight ratio, so it assumes the density is the same as that of water (1 g/mL).
By following these steps and using the given information, you can calculate the concentration in ppm.
