The volume of the object is the difference in water level before and after the object is added, which is 10 ml (30 ml - 20 ml). The density of the object is mass divided by volume, so 2g / 10 ml = 0.2 g/ml. Therefore, the density of the object is 0.2 g/ml.
stop cheating on gizmos, fool. :)The Answer: The mass of the water in the graduated cylinder is equal to the mass of the object.lol
If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.
To determine the mass of a graduated cylinder, simply weigh it using an analytical balance or scale. Subtract the empty weight of the balance from the weight displayed when the cylinder is placed on it to obtain the mass of the graduated cylinder in grams.
If an object with a density below one is placed in water, it will float. This is because the density of the object is less than that of water, causing it to be buoyant and float on the surface.
The volume of the object placed in the water is 23 ml. This can be calculated by subtracting the initial water level (30 ml) from the final water level (53 ml).

The volume of the object can be determined by calculating the difference in water levels before and after the object was placed in the graduated cylinder. Initially, the volume was 88 mL, and after adding the object, it increased to 100 mL. Therefore, the volume of the object is 100 mL - 88 mL, which equals 12 mL.

remain the same
Higher than what ?? If the object's density is higher than the density of water, then the object sinks in the water.
The volume of the piece of metal is measured by the difference in the volume of water in the graduated cylinder before and after the piece of metal is placed in the cylinder. This is stated to be 36 - 20 = 16 mL. Density is defined to be mass per unit volume. Therefore, for this piece of metal the density is 163/16 = 10 g/mL. (Only two significant digits are justified, because the is the number of significant digits in the limiting datum 16.)
We both know it floats
an object will float on a denser liquid
The volume of the object placed in the water is 23 ml. This can be calculated by subtracting the initial water level (30 ml) from the final water level (53 ml).
If an object placed in water sinks - then it has a density greater than water.
