10-mL volumetric flask (An empty ) weighs 10.263 grams. The mass is 20.211 grams After filling to the mark with distilled water at the temperature of 20 degree Celsius,. determine the mass of H2O in the flask and it's the true volume at 20° C?(at 20°C the Density g/mL=0.9982071,20°C the volume of 1g of water (mL) corrected for buoyancy is 1.0029 )
