Question

You have four solutions of salt water. Solution 1 has 55 g of salt dissolved in 500 mL of water 19 a concentration of 0.21 g/mL. Solution 3 has 36 g of salt dissolved in 144 mL of water. Solutio concentration of 0.23 g/mL. Which of the following lists the solutions in order from the leastc the most concentrated?

a 1, 2, 3, 4
c. 1, 2, 4,3
b. 2, 4, 3, 1
d. 3, 4, 2, 1

Answer 1

After calculating the concentration of each solution, Solution 1 has a concentration of 0.11 g/mL and Solution 3 has a concentration of 0.25 g/mL. Without further information, we cannot calculate the concentration for Solution 2 and Solution 4. Therefore, the order from least to most concentrated, based on given data, is Solution 1, Solution 3.

Step-by-step explanation:

To determine the order of concentrations from least to most, we will calculate the concentration of each salt water solution by dividing the mass of the salt by the volume of the solution.

For Solution 1, we have 55 g of salt in 500 mL of water. The concentration is given as 0.21 g/mL, which is correct since 55 g / 500 mL equals 0.11 g/mL (not 0.21 g/mL as stated in the question, likely a typo). For Solution 3, we have 36 g of salt in 144 mL of water. To find the concentration for Solution 3, we divide 36 g by 144 mL to get 0.25 g/mL.

With the concentrations calculated for Solution 1 and Solution 3, we can compare them. Since Solution 3 has a higher concentration (0.25 g/mL) than Solution 1 (0.11 g/mL), we can infer the order of the two solutions in terms of concentration from least to most: Solution 1, Solution 3. Note that Solution 2 and Solution 4 do not have enough information provided for a definitive order to be determined.
