A solution was made with 200g salt and 2,000 mL of water. Another container had 5,000 mL of water. How much salt would need to be added to make them have the same concentration?
200 g
1000 g
5,000 g
500 g
Two students make two solutions. Solution 1= 50 mL of water and 24g of solid. Solution 2= 100mL of water and 12g of the same solid. They put the two cups on either side of a balance to find out which solution is more concentrated.
What is wrong with this procedure?
The should have evaporated the liquids before weighing them.
They should have used different solids to make the solutions.
They should have compared equal volumes of the two solutions.
They followed a procedure to find density, not concentration.
If Solution 1 has 2 spoonfuls of solid and 100 mL of water and Solution 2 has 6 spoonfuls of solid and 300 mL of water, how do the concentrations compare?
Solution 1 > Solution 2
Solution 1 < Solution 2
Solution 1 = Solution 2
Not enough information to find the answer
