Consider two options for cleaning a paint brush. In each option the brush contains 5.0 mL of paint and you have 0.30 L of solvent. The brush retains 10 mL of dirty solvent after cleaning. Dirty solvent is defined as solvent that contains paint.

Option 1: The paint brush is washed in a container containing 0.30 L of solvent. The brush is withdrawn and the solvent on the brush evaporates.

Option 2: The solvent is divide into three containers in 0.10 L aliquots. The brush is washed in the first container, withdrawn and washed in the second container, and then withdrawn and washed in the third container. The solvent retained by the brush does not evaporate before the brush is washed in the second and third containers. Finally, the brush is withdrawn from the third container and the solvent evaporates.

Calculate the amount of paint that remains on a brush with options 1 and 2.
