Subtracting the mass of (flask+water) from the empty flask gives: 95.023 g - 85.135 g = 9.888 grams of water Dividing this by the given volume of 10.00 mL water gives: 9.888 grams of water / 10.00 mL of water = 0.9888 g/mL of water Therefore, based on this sample, the density of water is 0.9888 g/mL, which is close to the usually accepted approximation of 1 g/mL.
