Which solution has the highest concentration?

Question

Group of answer choices

100 grams of salt dissolved in 1,000 mL of water

10 grams of salt dissolved in 10,000 mL of water

100 grams of salt dissolved in 100 mL of water

10 grams of salt dissolved in 100 mL of water

Answer 1

To find which solution has the highest concentration, we can calculate the concentration of salt (in grams) per liter of solution for each option.

1. 100 grams of salt dissolved in 1,000 mL of water:

   • Concentration = 100 grams / 1 L = 100 g/L

2. 10 grams of salt dissolved in 10,000 mL of water:

   • Concentration = 10 grams / 10 L = 1 g/L

3. 100 grams of salt dissolved in 100 mL of water:

   • Concentration = 100 grams / 0.1 L = 1,000 g/L

4. 10 grams of salt dissolved in 100 mL of water:

   • Concentration = 10 grams / 0.1 L = 100 g/L

Now, let's compare the concentrations:

• First option: 100 g/L
• Second option: 1 g/L
• Third option: 1,000 g/L
• Fourth option: 100 g/L

The solution with 100 grams of salt dissolved in 100 mL of water has the highest concentration at 1,000 g/L.
