A flask has a mass of 7823g when empty and 593.63g when filled with water.when the same flask is filled with concentrated sulfuric acid(H2SO4) its the mass is 1026.57g . what is the density of concentrated sulfuric acid ? assume water has a density of 1.00g/cmcube at the temperature of the measurement.

Is that 78.23 or 7823 g?


We first compute the Volume of the flask. We use the formula: Density = Mass/Volume. We first compute the mass of water in the flask: 593.63 g - 78.23 g = 515.4 g. We plug the values in the formula: (1.00 g/cm^3) = (515.4 g) / V; V = 515.4 cm^3. Now we have the volume, we can now compute the density of the Sulfuric Acid: Density = (1026.57 g - 78.23 g) / (515.4 cm^3) = 1.84 g/cm^3.
