A flask 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

1840.01  kg/m³

Explanation:

From Archimedes's principle.

mass of H₂SO₄/ mass of water = Density of H₂SO₄/Density of water.

M/M' = D/D' Equation 1

Where M = mass of H₂SO₄, M' = mass of water, D = Density of H₂SO₄, D' = Density of water.

make D the subject of the equation

D = D'(M/M') Equation 2

Given: M' = 593.63-78.23 = 515.4 g = 0.5154 kg, M = 1026.57-78.23 = 948.34 g = 0.94834 kg, D' = 1000 kg/m₃

Substitute into equation 2

D = 1000(0.94834/0.5154)

D = 1840.01 kg/m³

Hence the density of concentrated sulfuric acid = 1840.01 kg/m³
