Density is equal to mass over volume.
Your volume is 82 ml.
What is the mass of water?
It should be [mass water + mass cylinder] - mass cylinder
Density = [123.1 - 41.6] / 82 = 0.99 gram/ml
Best answer?

The density of water at 4 degrees C is 1. Some people here are saying that the density of water at room temperature is 1 but that is not true (although it is probably close to 1).
To solve your problem subtract the mass of the empty cylinder from the mass of the cylinder with water in it to get the mass of the water (81.5g). THat number divided by 82mls will give you the density in g/ml.

At room temperature, it is 1 gm/ml.
Density=Mass/Volume
If we substitute values we gt
Density= (123.1-41.6)/82
= 81.5/82
=0.9939 mL

The density of room temperature water is always 1 g/cm3.

as Density =mass/volume
as the mass changes volume remains constant.
Density should vary.
but i dont think so the density will vary .
Density varies according to the temprature of surroundings.

123.1-41.6=81.5g
81.5/82=.994 g/mL
