A lead ball is added to a graduated cylinder containing 30.8 ml of water, causing the level of the water to increase to 89.9 ml.
enot [183]

A lead ball added to a graduated cylinder containing 30.8 ml of water, causing the level of the water to increase to 89.9 ml, has a volume of 59.1 ml.

Volume is defined as the amount of space that matter occupies. There are three different ways to find the volume:

1) Volume by Space - by measuring its physical dimensions

2) Volume by Density and Mass - by dividing its weight by its density

3) Volume by Displacement - by measuring the volume displaced when immersed in a liquid or gas

To solve for the volume of the lead ball, we can use the displacement method by subtracting the initial volume from the final volume.

If the level of the water increased from 30.8 ml to 89.9 ml upon adding the lead ball, the displaced volume is:

volume = final volume - initial volume

volume = 89.9 - 30.8

volume = 59.1 ml

Hence, the volume of the lead ball, using displacement method, is 59.1 ml.

Suppose 35 mg of benzoic acid is dissolved in 7 mL of dichloromethane. The resulting organic solution is then extracted with
olga nikolaevna [1]

Answer:

Kp = 13.3

Explanation:

Partition coefficient is used to extract or purify a solute from a solvent selectively to avoid interference from other substances. The formula is:

Kp = Concentration of solute in organic solvent / Concentration of solute in H₂O

As the CH₂Cl₂ is containing 31mg, water is containing 4mg. Replacing in the formula:

Kp = (31mg/7mL) / (4mg/12mL)

<h3>Kp = 13.3</h3>
