Part I: Calculating Density

How is the density of a substance calculated?

If the shape of an object is irregular, like a stone, how can you measure its volume?

If the volume of a cube of wood is15.625 cm3 and its mass is 10.00 grams, show the calculation for the density of the wood.

Based on the density of the wood that you calculated above, would the wood float or sink if it is placed in a bowl of water? Explain your answer. Remember that the density of liquid water is 1.00 g/cm3.

A marble or small sphere, made of stone, is found to have a mass of 3.05 grams. To find its volume, it is placed in a graduated cylinder that originally contains 10.00 mL of water. When the marble is placed in the graduated cylinder, the new volume of the water and marble together is 11.20 mL.
a. Calculate the volume of the marble (Be sure to include units).

b. Calculate the density of the marble (Be sure to include units).

Answer 3

\[D=M \div V\]

Answer 4

Can u help me with the rest

Answer 5

@Angel_Halo23

Answer 6

\[D=M \div V\]
\[D=10.000 \div 15.625\]
\[D=.64g/cm^3\]

Answer 7

that last one was for the wooden cube problem

Answer 8

the wood would float

Answer 9

and I've forgotten how to do the rest b/c it's been so long since I have done it
