NaOH is one molecule (sodium hydroxide). The coefficient (20) is telling you that there are 20 molecules of NaOH. Sodium hydroxide is composed of one sodium atom (Na), one oxygen atom (O), and one hydrogen (H) atom. If one molecule has three atoms, then 20 molecules will have 60 atoms total.

What an Atoms identity?
The number of protons in the nucleus of the atom determine its identity.
How do you determine the number of atoms in a coin?
You need to know what elements the coin is made up of (ie. what percent is iron and what percent is copper). You'd then need to weigh the coin out. If you wanted to know how many iron atoms there are, then you'd calculate how much iron there is and convert that to moles and then to atoms using avogadro's number.
How many total atoms are in Sq2R3?
To determine the total number of atoms in the chemical formula Sq2R3, you need to consider the subscripts. The formula indicates there are 2 atoms of element Sq and 3 atoms of element R. Therefore, the total number of atoms is 2 (from Sq) + 3 (from R) = 5 atoms.
How many atoms in 19.3 grams of gold on a sheet that is 0.00010?
To calculate the number of atoms in 19.3 grams of gold, you need to first determine the number of moles of gold. Then, you can use Avogadro's number (6.022 x 10^23) to find the number of atoms. Given that the sheet is only 0.00010 cm thick and the density of gold is 19.3 g/cm^3, you can determine the area of the sheet and then calculate the number of atoms.
How many atoms of the daughter product would you expect to be present?
To determine the number of atoms of the daughter product, you need to know the initial quantity of the parent isotope and the decay rate or half-life. The number of daughter atoms formed is equal to the number of parent atoms that have decayed. If the system is in equilibrium, the number of daughter atoms can equal the number of parent atoms that have decayed over time. Without specific values or context, an exact number can't be provided.
How can you determine an atoms identity?
By the number of protons it has.
How do you determine the numbers of atoms in a chemical equation?
It is necessary to balance the number of atoms for reactantas and products.
What does the number of protons in a atoms's nucleus determine?
try counting
How does oxidation numbers determine the number of atoms?
Oxidation numbers indicate the charge of an atom in a compound. By comparing the oxidation numbers of different atoms in a compound and knowing their charges, you can determine the number of atoms involved in the reaction or compound. These numbers help balance chemical equations and determine the stoichiometry of a reaction.
What an Atoms identity?
The number of protons in the nucleus of the atom determine its identity.
What is the answer. Determine the number of atoms in 3.29 mol Zn?
To determine the number of atoms in 3.29 mol of Zn, you would use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Multiply the number of moles (3.29 mol) by Avogadro's number to find the number of atoms. The calculation would be: 3.29 mol Zn x 6.022 x 10^23 atoms/mol = 1.98 x 10^24 atoms of Zn.
What does the number of atoms in the nucleus determine?
Do you mean number of protons in a nucleus? The nucleus is part of an atom.
How many atoms of carbon are present in the reactants?
To determine the number of carbon atoms in the reactants, you need to specify which reactants you are referring to. The number of carbon atoms can vary depending on the chemical equation.
How many atoms are present in 80.0 mol of zirconium?
To determine the number of atoms in 80.0 mol of zirconium, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Multiply 80.0 mol by Avogadro's number to find the total number of atoms in 80.0 mol of zirconium.
How many grams atoms of sulfur are there in g of sulfur?
To determine the number of grams atoms of sulfur in a given mass of sulfur (g), you need to calculate the number of moles of sulfur first. Then, you can use Avogadro's number to convert moles to atoms. Finally, multiply the number of moles by Avogadro's number to find the number of atoms.
What part of an atom can be used to determine if two atoms are the same element?
Number of protons.
How can one determine the number of chiral centers in a molecule?
To determine the number of chiral centers in a molecule, one must identify carbon atoms that are bonded to four different groups. These carbon atoms are considered chiral centers because they have a non-superimposable mirror image. Counting the number of these carbon atoms in the molecule will give you the total number of chiral centers.
