Mohamed · Answer 1

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.
