parts per million 63 grams of HNOs is dissolved in enough water to make 100 liters of solution

Answer 1

To convert 63 grams of HNO3 to parts per million (ppm) in a solution of 100 liters, we can use the following formula:

ppm = (mass of solute / mass of solution) * 10^6

First, we need to calculate the total mass of the solution:

63 grams of HNO3 is dissolved in enough water to make 100 liters of solution. The density of water is approximately 1 g/mL, so 100 liters of water is equivalent to 100,000 grams.

Total mass of solution = 63 grams + 100,000 grams = 100,063 grams

Now, we can calculate the concentration of HNO3 in ppm:

ppm = (63 grams / 100,063 grams) * 10^6
ppm = 0.000629846 * 10^6
ppm = 629.846 ppm

Therefore, 63 grams of HNO3 dissolved in 100 liters of solution results in a concentration of approximately 629.846 ppm.
