Calculate the concentration in parts per million (ppm) of the solute in each of the following aqueous solutions
(a) 0.00500 g of sodium chloride in 850 mL of solution
I do ppm by mg/L.
0.005g/850 = 5 mg/850 mL
5 mg x (1000/850) = mg/L = ppm.
Well, let's first convert the mass of sodium chloride to milligrams. So, 0.00500 g = 5000 mg.
Now, let's calculate the concentration in ppm using the formula:
Concentration (ppm) = (Mass of solute / Volume of solution) * 10^6
Concentration (ppm) = (5000 mg / 850 mL) * 10^6
Concentration (ppm) = (5000 mg / 850 mL) * 10^6
Concentration (ppm) = 5882.35 ppm
So, the concentration of sodium chloride in this solution is approximately 5882.35 ppm. Remember, always keep a sense of humor, even when calculating concentrations!
To calculate the concentration in parts per million (ppm), we need to determine the ratio of the solute (in grams) to the solution volume (in milliliters) and multiply it by 1,000,000.
First, we need to convert the mass of the solute from grams to milligrams. Since there are 1000 milligrams (mg) in 1 gram, the mass of sodium chloride is 0.00500 g * 1000 = 5.00 mg.
Next, we divide the mass of the solute by the volume of the solution in milliliters and multiply by 1,000,000 to obtain the concentration in ppm.
Concentration in ppm = (5.00 mg / 850 mL) * 1,000,000
Concentration in ppm = 5882 ppm
Therefore, the concentration of sodium chloride in this solution is 5882 ppm.
To calculate the concentration in parts per million (ppm) of the solute in a solution, you need to determine the mass of the solute and divide it by the mass of the solution, then multiply by 1,000,000.
In this case, we have 0.00500 g of sodium chloride in 850 mL of solution. However, before we can proceed with the calculation, we need to convert the volume of the solution from milliliters (mL) to grams (g) because mass is typically measured in grams.
To convert mL to grams, we need to know the density of the solution, as different solutions have varying densities. Once we have the density, we can multiply the volume (850 mL) by the density to get the mass in grams.
Let's assume that the density of the solution in this case is 1 g/mL (which is close to the density of water). Multiplying the volume (850 mL) by the density (1 g/mL), we get:
850 mL * 1 g/mL = 850 g
Now we have the mass of the solution as 850 g.
Next, we divide the mass of the solute (0.00500 g) by the mass of the solution (850 g):
0.00500 g / 850 g = 0.00000588
Finally, multiply the result by 1,000,000 to convert it to parts per million (ppm):
0.00000588 * 1,000,000 = 5.88 ppm
Therefore, the concentration of sodium chloride in this aqueous solution is 5.88 ppm.
