What is the density of 12.5 g and 5.0 ml of water?

To calculate the density of a substance, you divide its mass by its volume. For 12.5 grams of water in 5.0 milliliters, the density would be calculated as follows: Density = Mass/Volume = 12.5 g / 5.0 ml = 2.5 g/ml. Therefore, the density of the water is 2.5 g/ml.
