Answer:
Density of concentrated H2SO4 = 1.99g/cm^3 = 1991.79Kg/m^3
Explanation:
mass of empty flask = 78.23g mass of flask filled when with water = 593.63g.
mass of flask filled when with concentrateds sulfuric acid, H2SO4 = 1026.57g
Mass of water = (mass of flask filled when with water) -
(mass of empty flask) = 593.63g - 78.23g = 515.4g
Volume of flask = volume of water = volume of concentrateds sulfuric acid, H2SO4 =
(mass of water)/ density of water) = 515.4g/1.00g/cm^3 = 515.4cm^3
The density of concentrated sulfuric acid is given by
Density of concentrated H2SO4 = (mass of H2SO4) ÷ (volume of H2SO4) = 1026.57g/515.4cm^3 = 1.99g/cm^3 = 1991.79Kg/m^3

Since the question is incomplete the complete question is as follows:
Formalin and methanal are both synonymous with formaldehyde. True or false?
Formalin as well as methanal are the chemical terms that are used for formaldehyde. Thus, the given statement is true.
- Formalin is the trade name of formaldehyde.
- Formaldehyde (HCHO) is also called as methanal. It is an organic compound which is simplest forms of aldehyde.
- It is mainly used for manufacturing processes related to chemicals.
- Formaldehyde is produced by the vapor phase oxidation of substrate methanol.
Hence, the given statement is true formalin and methanal are called as formaldehyde.
