Answer:
Explanation:
Moles of NaCl :
Given, Mass of NaCl = 72.24 g
Molar mass of NaCl = 58.44 g/mol
The formula for the calculation of moles is shown below:
Thus,
NaCl is a strong salt. So, moles of chloride ion = 1.2361 moles
Volume = 0.862 L
Answer:
The weight of the objects has a name and is "Specific weight", this is measured in several measurements but the best known is the kg.
If we relate the density of the object with the weight we will obtain a deduction of the shape of the object.
Explanation:
The object can be more or less heavy according to its density and its chemical composition.The weight is nothing more than the attraction of that object with the interior of the earth, that is why in order to know well how heavy it is, it is necessary relate the density of the object, the material that composes it, the speed of gravity (10m / s2).
This refers to the fact that a kilo of feather is not the same as a kilo of lead, each object obtains its shape according to the more weight it has and the more attraction it can make to the center of the earth.
