Back

Solution B

Front

What did the student do wrong when comparing solutions on a balance?

Back

She should have measured out the same volume of each solution before putting them on the balance.

Front

List the solutions in order from most concentrated to least concentrated: Green Solution= 50 mL of water and a mass of 75g; Blue Solution=50 mL of water and a mass of 31 g; Orange Solution=50mL of water and a mass of 50 g; Purple Solution=50 mL of water and a mass of 63 g.

What is concentration?

Back

the ratio of solute to solvent

Front

True or False? The more concentration = higher density

Back

True

Front

A student measured out equal volumes of 2 solutions and put them on a balance. Which statement is true?

Back

The solution with the higher mass is more concentrated.
