Unformatted text preview: A and 58.63 B by volume, what is the density of the metal? What assumptions must be made in applying this method? Question 3: An empty flask weighs 38.2567 g. When it is filled with water, it weighs 55.1437 g. When it was filled with an unknown liquid, it weighs 58.1735 g. Calculate the density of this liquid (Density of water = 0.9980 g/mL). Question 4: Calculate the following and pay attention to the significant figures. (28.21 1.0) x 0.157/0.124 Question 5: Carry out the following conversions: (1) kg/L to g/mL, (2) kg/m 3 to g/cm 3 , and (3) eV to kJ/mol. Question 6: Prove that the intensity ratio of the m/e 78 peak to the 79 peak is 98.9:6.6 in the mass spectrum of benzene....
