Answer:
A solution of salt water is made by dissolving 2 grams of salt in 1 liter of water. Which of the following would yield a solution with the same concentration
a) dissolving 1/2 gram of salt in 2 liters of water
b) dissolving 1/2 gram of salt in 1/2 liter of water
c) dissolving 1 gram of salt in 1/2 liter of water
d) dissolving 1 gram of salt in 2 liters of water
e) dissolving 2 grams of salt in 1/2 liter of water.
Explanation:
In this activity we have to determine which solution would have the same concentration of the one presented above. In the example we have a solution of 2 grams of salt for 1 liter of water, which means that for every liter of water there are 2 grams of salt, which would make a 2:1 ratio. Therefore for every 1/2 liter of water there is 1 gram of salt. The only option where the 2:1 ratio is maintained is option c) dissolving 1 gram of salt in 1/2 liter of water.
