Hello!
The density of water is 1 g/mL.
Explanation:
There isn't enough data in your question, but I'll show you how to calculate the density of water from measurings using a graduated cylinder.
You probably measured the mass of the empty cylinder (Mec), then add a known volume of water (V) and after that, you measured the mass of the cylinder with water (Mwc). From this data, it's easy to calculate the density of water, using this formula:
[tex] density=\frac{Mwc-Mec}{V} [/tex]
The value you get should be close to 1 g/mL
Have a nice day!
