Question

to transform marble in plaster we need attack it with acid sulfuric after this reaction H2SO4 CaCO3->CaSO4 CO2 H2O

using 2kg of marble,which the mass of plaster we can have

Answer 1

Moles CaCO3 = 2000 g / 100 g/mol =20

The ratio between CaCO3 and CaSO4 is 1 : 1

Moles CaSO4 = 20

Mass CaSO4 = 20 mol x 136 g/mol =2720 g = > 2.7 Kg
