If every gram of salt is 20.9% chlorine, how much is required to make a 220 ppm chlorine solution with 350 grams of water?
1 answer:
Answer:
The amount of salt required is 0.3685 grams.
Step-by-step explanation:
20.9% of 1 gram of salt is chlorine, which means the grams of chlorine in 1 gram of salt are
Now, to make 220 ppm solution, it must be that
where is the grams of chlorine required.
We rearrange the equation and solve for
since 1 gram of salt has 0.209 grams of chlorine, 0.07702g of chlorine corresponds to
Thus the amount of salt required is 0.3685 grams.

1. . Exponential decay function.
2. . Exponential growth function.
3. . Exponential growth function.
4. . Exponential growth function.
5. . Exponential growth function.
6. . Exponential decay function.
7. g(x) = 0.3(x). Not an exponential function.
Step-by-step explanation:
1. . This is an exponential decay function.
As the value of t increases H-value decreases.
2. . This is an exponential function of growth.
As the value of t increases y-value also increases.
3. . This is an another example of exponential growth function.
As the value of t increases f(t)-value also increases.
4. . This is again an example of exponential growth function.
As the value of t increases A-value also increases.
5. . This is again an example of exponential growth function.
As the value of t increases A-value also increases.
6. . This is another an example of exponential decay function.
As the value of t increases, H-value decreases.
7. g(x) = 0.3(x). This is a non-exponential function. (Answer)
