Jonathan wants to find the density of a lead fishing weight. He measures the weight's mass at 342.0 grams. He then puts the lead weight into a graduated cylinder filled with 200 milliliters of water. He sees that the water level rises to 240.0 milliliters. What is the density of the lead weight?

A) 440mL

B) 542g/mL

C) 0.78g/mL

D) 8.55g/mL

Can someone please explain this to me?

Answer :

Answer:

The answer is option D

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass = 342 g

volume of lead = final volume of water - initial volume of water

volume = 240 - 200 = 40 mL

We have

[tex]density = \frac{342}{40} = \frac{171}{20} \\ [/tex]

We have the final answer as

8.55 g/mL

Hope this helps you
