Question

Shaila is collecting data to calculate the density of a piece of wood. First, she

places the wood on a triple beam balance; its mass is 63.85 g. Then, she fills a
graduated cylinder with 50.0 mL of water. She places the wood in
graduated cylinder with the water and notes that the water level rises to 125.0
mL. Calculate the density of the wood given that D = m/V. i need some1 to explain this

Answer 1

Step-by-step explanation:

Remark

You have 2 facts that you got from the experiment. The first is that the mass of the wood is 63.85 grams and the volume can be calculated.

From there, the desity can be found.

Givens

m = 63.85 grams

vo = 50 mL

vf = 125 mL

Solution

Volume = vf - vo

Volume = 125 mL - 50 ml. This gives you the amount of water that has been moved aside (called displaced)

volume = 75 mL

D = 63.85 grams/ 75 mL

D = 0.851 grams / mL

Some woods actually do have a density less than 1 which is the density of water. These woods float.
