A graduated cylinder was filled with 25.0 mL of water. A solid object was immersed in the cylinder, raising the water level to 3

yawa3891 [41]

Answer:

Density of the object is 8759.494 grams/L

Explanation:

As we know density of an object is mass of the object divided by its volume

Given

Volume of the object is equal to the change in volume of water with in the cylinder when the object was immersed in water.

Hence, volume of object is equal to

$32.9 -25 = 7.9$ mL

Mass of the object is $69.2$ grams

Density

$= \frac{69.2}{7.9 *10^{-3}}\\= 8759.494$ grams/L

Density of the object is 8759.494 grams/L
