Bill finds an unusual object and wishes to calculate it's density. He discovers a problem of accurately weighing it, because it won't stay on the weighing pan. To solve this he adds the object to a beaker containing 190 mL of distilled water and finds the water level rises to 256 mL. The flask of water weighed 1066.3 grams after the object was added. If the empty beaker weighed 749 grams, calculate the following:

The weight of the water: g
The weight of the object: g
The volume of the object: cm3
The density of the object: g/cm3

How much of this can you do by yourself? How much have you done? What exactly do you not understand about it?

i don't know any of this

To calculate the weight of the water, we need to subtract the weight of the empty beaker from the weight of the beaker with water and the object.

Weight of the water = Weight of beaker with water and object - Weight of empty beaker

Weight of the water = 1066.3 g - 749 g

Weight of the water = 317.3 g

So, the weight of the water is 317.3 grams.

To calculate the weight of the object, we need to subtract the weight of the water from the weight of the beaker with water and the object.

Weight of the object = Weight of beaker with water and object - Weight of water

Weight of the object = 1066.3 g - 317.3 g

Weight of the object = 749 g

So, the weight of the object is 749 grams.

To calculate the volume of the object, we can use the principle of displacement. The increase in water volume when the object is added to the beaker represents the volume of the object.

Volume of the object = Final water volume - Initial water volume

Volume of the object = 256 mL - 190 mL

Volume of the object = 66 mL

Since 1 mL is equivalent to 1 cm³, the volume of the object is 66 cm³.

To calculate the density of the object, we can use the formula:

Density = Weight / Volume

Density = 749 g / 66 cm³

Density ≈ 11.35 g/cm³

So, the density of the object is approximately 11.35 g/cm³.

the weight of the water is 256ml

i don't know The weight of the object
The volume of the object, or The density of the object.
