Date 9/2/19 Section 193 I. Density of Water Trial 1 Trial 2 Mass of beaker, s Mass of beaker + water, g Mass of water, g Volume of water, mL Density of water, g/mL 10.00mL 60.5049 60.5269 70.4069 70.4089 70.4069 - 60.5269 9.9049 9.8809 - 9.88 10.00mL 10.00mL 0.9904 g/mL 0.9880g/ml 9.8809-01 Show your calculation for the density of the water. 70.4089 d= mass - de 9.9099-09 - 60.5049 10.00mL 9.904g Average density of water, g/mL Was the mass of the beaker the same for the two trials? No 0.98929, 0.99048 IML If not, what would account for the difference? the water mass righ H₂U 2 Bernal If there was a difference, will it affect your results for the density in Trial 2? Explain. yes because the density was different. N AFRET REPORT SHEET 33

Answer 1

amsi Human error may likely to account for the difference. or the beaker may not be dried completely. or the surroundi angs condition may not be the same as in previous one. Ams: No there will be no effect in density as if there is error in mass of beaker, there will be same error in mass of beaker twater. When we subtract both the error will get cancelled out and accurate mass of water is obtained.
