The density of marble is between 2.6 and 2.8 grams per cm³ .
Density doesn't depend on how much mass or volume of it you have.
The density of a chip of it is the same as the density of a truckload of it.
All pieces will be 17 g/cm^3 because the density is not affected by cutting (assuming the rock is uniform).
You may find bellow the balanced chemical reactions.
Explanation:
To balance chemicals equation the number of atoms of each element
entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.
2. Single displacement: Zn + 2 HCl → ZnCl₂ + H₂
3. Decomposition: NiCl₂ → Ni + Cl₂
4. Double displacement: 2 LiI + Pb(NO₃)₂ → PbI₂ + 2 LiNO₃
5. Double displacement: BaCl₂ + H₂SO₄ → BaSO₄ + 2 HCl
6. Single displacement: Cu + 2 AgNO₃ → Cu(NO₃)₂ + 2 Ag
7. Synthesis (combination): 2 Na + O₂ → 2 Na₂O
8. Solid mercury (II) oxide decomposes to form liquid mercury and oxygen.
2 HgO (s) → 2 Hg (l) + O₂ (g) (decomposition reaction)
9. A solution of zinc hydroxide reaction with phosphoric acid (H₃PO₄) to produce solid zinc phosphate and water.
3 Zn(OH)₂ + 2 H₃PO₄ → Zn₃(PO₄)₂ (s) + 6 H₂O (l) (double displacement reaction)
where:
(s) - solid
(l) - liquid
