Molarity= (number of moles of that substance) / (Volume of solution in litres)
7= (number of moles of HCl) / 0.05
Thus,
Number of moles of HCl = 7 x 0.05 = 0.35
The number of moles of HCl will remain unchanged.
Now, for new solution,
0.35= 0.35 / (New volume of solution in litres)
Thus,
New volume = 1 litre
Thus, amount of water added = 1- 0.05 litre = 5.0 M
Explanation:
Limostone is a sedimentary rock composed mainly of calcium carbonate (CACO3),generally calcite,although it frequently has traces of magnesite (MGCO3)and others carbonates.
<span>The energy in coal comes from energy that was
stored in giant plants that lived hundreds of millions of years ago in
swamp forests, even before the dinosaurs! When these giant plants and
ferns died, they formed layers at the bottom of the swamps. Water and dirt began to pile up on top of the dead plant remains.</span>
