Aflask has a mass of 78.23 g when empty and 593.63 g when filled with water. when the same flask is filled with concentrated sulfuric acid, h2so4, its mass is 1026.57 g. what is the density of concentrated sulfuric acid? (assume water has a density of 1.000 g/cm3 at the temperature of the measurement.

This problem is solved in three steps.

First step: determine the volume of the flask.

Second step: determine the mass of sulfuric acid.

Third step: divide the mass of sulfuric acid by the volume to calculate the density.

1) Volume of the flask

1a.- mass of water in the flask, m1 = mass of the flask with water - mass of the empty flask

m1 = 593.63 g - 78.23 g = 515.4 g

1b.- density = mass / volume => volume = mass / density = 515.4 g / 1.000 g/cm^3

volume = 515.4 cm^3.

2) Mass of sulfuric acid, m2

m2 = 1026.57 g - 78.23 g = 948.34 g

3) Density = mass / volume

Density = 948.34 g / 515.4 cm^3 = 1.840 g / cm^3.

1.840 g/cm^3

 

Idid the calculation and i get 875,000,000 which can be written as 8.75 x 10^6?
