Answer:
0.5
L solution
⋅
required molarity
2.5 moles NaCl
1
L solution
=
1.25 moles NaCl
Now, to convert this to grams of sodium chloride, you must use the mass of
1
mole of this compound as a conversion factor. The mass of
1
mole of sodium chloride is given by its molar mass
1.25
moles NaCl
⋅
58.44 g
1
mole NaCl
=
73 g

Explanation: if this is wrong i am very sorry
<span>has four valence electrons in its outermost energy level.
An organic compound in which a carbonyl group is bonded to two different carbon atoms is a(n) ketone.
All of the following release carbon into the atmosphere except the

Rutherford theorized that atoms have their charge concentrated in a very small nucleus.
This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).
Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.
That is different from Plum Pudding model, because it shows that most of the atom is empty space.
According to Rutherford model of the atom:
1) Atoms have their charge concentrated in a very small nucleus.
2) Major space in an atom is empty.
3) Atoms nucleus is surrounded by negatively charged particles called electrons.
4) An atom is electrically neutral.
25° C is the temperature required for the cell potential to be the standard cell potential
