72.0 grams NaCl (1 mole NaCl/58.44 grams)
= 1.2 moles of sodium chloride
there are 4.5 moles
How many formula units of sodium acetate are in 0.87 moles of sodium acetat
The balanced equation for the reaction is AgNO3 (aq) + NaCl (aq) -> AgCl (s) + NaNO3. The coefficient of each reactant is the implied 1 when no explicit coefficient is shown in the equation. Therefore the same number of moles of silver nitrate as of sodium chloride are required for the reaction.
.73 moles
the formula does not show how many moles are in a compound, but it tells how many atoms of an element that are in the compound...
The answer is 0,111 moles.
Every formula unit of sodium chloride has one sodium atom. Therefore, there are 4.0 moles of sodium ions in 4.0 moles of NaCl.

How many formula units of sodium acetate are in 0.87 moles of sodium acetat
Sodium in its elemental form is just sodium metal, Na. Thus assuming that the sample of sodium is pure, there are 2.50 moles of sodium in a 2.50mol sample.
The balanced equation for the reaction is AgNO3 (aq) + NaCl (aq) -> AgCl (s) + NaNO3. The coefficient of each reactant is the implied 1 when no explicit coefficient is shown in the equation. Therefore the same number of moles of silver nitrate as of sodium chloride are required for the reaction.
5,25 moles (in anhydrous sodium sulphate)
There are two moles of sodium ions in two moles of sodium chloride.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
The answer is 0,175 moles.
Sodium has 12 neutrons. Chloride ion has 18 neutrons. In a formula unit, NaCl has 30 neutrons.
