NaC2H3O2
14.5 g NaC2H3O2 (1 mole NaC2H3O2/82.034 grams)(6.022 X 10^23/1 mole NaC2H3O2)
= 1.06 X 10^23 atoms of sodium acetate
The formula for cobalt acetate is Co(C2H3O2)2. According to the formula, there are four carbon atoms in each formula unit. When an ion is in parentheses, you multiply the subscripts inside the parentheses times the subscript outside the parentheses to find the total number of atoms of an element.
Mg(C2H3O2)2 or magnesium acetate has one magnesium atom, four carbon atoms, six hydrogen atoms and four oxygen atoms. So a total of 15 atoms per molecule of magnesium acetate.
The formula for sodium sulfate is Na2SO4. Therefore, there are 2 sodium atoms, one sulfur atom, and 4 oxygen atoms, for a total of 7.
21 atoms
Yes, the reaction of sodium and chlorine obeys the law of conservation of matter. This law states that matter is neither created nor destroyed in a chemical reaction. In the reaction between sodium and chlorine, sodium atoms combine with chlorine atoms to form sodium chloride. The total number of atoms before and after the reaction remains the same, demonstrating the conservation of matter.
Sodium acetate has a total of 8 atoms Sodium=1 Carbon=2 Hydrogen=3 Oxygen=2 The formula is NaCH3COO
The correct formula of sodium chloride is NaCl. This molecule has two atoms - sodium and chlorine.
The formula for cobalt acetate is Co(C2H3O2)2. According to the formula, there are four carbon atoms in each formula unit. When an ion is in parentheses, you multiply the subscripts inside the parentheses times the subscript outside the parentheses to find the total number of atoms of an element.
1 Na atom 1 H atom 1 C atom 3 O atoms _________ 6 atoms in total
Mg(C2H3O2)2 or magnesium acetate has one magnesium atom, four carbon atoms, six hydrogen atoms and four oxygen atoms. So a total of 15 atoms per molecule of magnesium acetate.
The formula for sodium sulfate is Na2SO4. Therefore, there are 2 sodium atoms, one sulfur atom, and 4 oxygen atoms, for a total of 7.

the total number of subshell for a sodium atom is 4.
The number of elementary entities in a mole of the substance. The elementary entities depends on the particles making up the substance. For example, argon is made of single atoms, so a mole of argon simply contains Avogadro's number of atoms. Water, on the other hand, is made of molecules, so a mole of water contains Avogadro's number of molecules. Now each water molecule, H2O, contains 3 atoms so a mole of water contains 3xAvogadro's number of atoms. Sodium chloride, NaCl, is made of sodium and chloride ions, in a ratio of 1:1. So a mole of sodium chloride contains Avogadro's number of sodium ions, and Avogadro's number of chloride ions. A mole of sodium chloride therefore contains 2xAvogadro's number of ions in total. The number comes from the number of carbon atoms in 12g of carbon-12.
NaHSO4 is a compound known as sodium hydrogen sulfate or sodium bisulfate. It has one sodium atom, one hydrogen atom, one sulfur atom and four oxygen atoms for a total of seven atoms.
This problem requires the atomic masses of each element involved. Then add them together to get the total molecular mass. If you take sodium's weight and divide it by the total mass, then you should have the percent of sodium in sodium chloride. Na- 23.0 Cl- 35.5 NaCl- 58.5 grams 23.0 / 58.5 × 100= 39.3% Na in NaCl Now we need to find the total number of atoms in the whole compound. Take the grams and convert it to atoms using Avogadro's constant. 11.2 g Na × (6.02 × 1023 atoms) / (23.0 g) Na = 2.93 × 1023 atoms If that is the total mass, then we know that 39.3% of it has to be sodium 39.3% of (2.93 × 1023)= 1.15 × 1023 atoms Na
molar mass of sodium = 23 number of mols = mass/ molar mass therefore 46g of Na = 2 mol
