ok so i have to find the density of a rubber stopper at school... I know density is mass/volume but how do i find this info with water, and a cylinder, and a scale
2)How do i find the volume of a droplet of water, i have tools like a cylinder, etc.
thanks! 10 points to best answer <3

well weigh the rubber stopper and fill a graduated cylinder to the 30mL line. Then place the rubber stopper in and see how much the rubber stopper has displaced the water. For example if you filled it to the 30mL line and the stopper displaces the water to the 35 mL line the volume taken up by the rubber stopper is 5mL.
Divide the weight of this stopper by the volume displaced and you have the density.
The volume could be found using a graduated cylinder. I recommend using a 10mL cylinder that way it will be easier to tell.
