The value of n is NaCO3: 0.103/0.07= 1.47 and
h2o: 0.07/0.07= 1.
What is a mole?
Mole, also spelled mol, in chemistry, standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
The mole designates an extremely the large number of units, 6.02214076 ×[tex]10^{23}[/tex] . The General Conference on Weights and Measures defined mole as this number for the International System of Units (SI) effective from May 20, 2019. The mole was previously defined as number of atoms determined experimentally to be found in 12 grams of carbon-12.
The number of units in a mole also bears name Avogadro’s number, or Avogadro’s constant, in honor of the Italian physicist Amedeo Avogadro (1776–1856). Avogadro proposed that equal volumes of gases under same conditions contain the same number of molecules, a hypothesis that proved useful in determining atomic and molecular weights and which led to the concept of the mole. (See Avogadro’s law.)
The number of atoms or the other particles in a mole is the same for all substances. The mole is related to mass of an element in the following way: one mole of carbon-12 atoms has 6.02214076 × [tex]10^{23}[/tex]atoms and a mass of 12 grams.
In comparison, one mole of oxygen consists, by definition, of same number of atoms as carbon-12, but it has a mass of 15.999 grams. Oxygen, therefore, has greater mass than carbon. This reasoning also can be applied to the molecular or formula weights.
The mass of anhydrous NaCO3 representing CO2 production is calculated:
m NaCO3 = 0.457*(106 NaCO3/ 44g co2)= 1.10g
Mass of water is calculated:
m h2o =1.85g-0.457= 1.393g
Moles of each component are calculated:
n NaCO3= 1.10/106 = 0.103 mol
n h2o = 1.393/18 = 0.07 mol
They are divided by smallest:
NaCO3: 0.103/0.07= 1.47
h2o: 0.07/0.07= 1
