From the Periodic Table, 1 mole of sodium is 22.989770g. To find the number of moles in 2.30g, multiply the known mass x (1mol/22.989770g).
2.30g Na X (1mol Na/22.989770g Na) = 0.100mol Na*
* The answer is in 3 significant figures because 2.30g has 3 significant figures. When you multiply or divide, the answer is rounded to the same number of significant figures as are found in the number with the fewest significant figures.

How many atoms are in 3.91 moles of sodium?
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
Number of oxygen atoms in 2.35 moles sodium phosphate?
17.54 mg
What would 124 sodium atoms weigh?
Sodium has an atomic mass of 29.990 g/mol. This means that 124 sodium atoms have a mass of 3718.76 amu, if the isotopes follow the average. To find in grams, the following must be used: 124 sodium atoms equal 2.0598 * 10-22 moles, so 124 sodium atoms have a mass of 6.177 *10-21 grams.
When 0.5 moles of Na2SO4 is dissolved in water how many moles of sodium ions are present?
Since the formula shows two sodium atoms in each formula unit of sodium sulfate and this compound normally completely ionizes in water solution, the number of sodium ions will be twice the number of moles of the salt; in this instance, 1.0 moles of sodium ions.
How many moles of sodium hydroxide are found in 120 grams of Na OH?
The mole of a metal, such as sodium, is generally assumed to consist of Avogadro's Number of single atoms. The gram atomic mass of sodium is 22.9898. The number of moles in 120 grams of Na is therefore 120/22.9898, or 5.22, rounded to the justified number of significant digits.
How many atoms of sodium are present in Moles of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
How many atoms of sodium are present in 3 moles of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
How many atoms of sodium are present in 3 mole of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
How to convert grams to atoms?
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
What is the amount of sodium atoms in 3.9 moles of sodium?
3.9 moles of atoms
How many atoms are in 4.0 moles of sodium?
1 mol has 6,022 140 857.10e23 atoms (The number of Avogadro).4 moles of sodium have 24,088 563 428.10e23 atoms.
How many mols of sodium are present in 45.48 g of sodium?
# of moles = Mass÷ Formula weight Example: 6 grams of Carbon atoms Carbon has an atomic mass of 12 grams so according to the Equation # of moles = 6÷ 12 = 0.5 moles For a compound such as CO2 , Formula weight = ( 1 mole of carbon atom weighs 12 grams + 2 moles of oxygen atoms weighs 32 grams ) 44 grams. Example: 24 grams of carbon dioxide = 24÷ 44 = 0.5454 moles So for sodium, # of moles = 45.48 g ÷ 22.99g/mole = moles You divide!
How many atoms are in 3.91 moles of sodium?
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
How do you convert atoms to grams with Avogadro's number?
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
How do you atoms to grams?
You find the number of atoms from the number of grams of a given substance by:Find the Moles of the Substance by multiplying the grams of the substance by the molar mass of the substance. ( Molar mass equals mass of substance per 1 mole of substance.)Grams x Molar Mass of Substance = Moles of SubstanceTake the moles of the substance and multiply it by Avogadro's Number (the number of atoms in 1 mole of substance, or simply 6.022x1023).Moles of Substance x Avogadro's Number (6.022x1023) = atoms of Substance
How many atoms of sodium are present in 3 moles of sodium and what is mass of it?
each mole contains 6.022*10(raised to the power 23) so three moles of sodium contain 18.066*10(raised to the power 23) mass of one mole of sodium is 11 grams so mass of three moles of sodium is 33 grams
Number of oxygen atoms in 2.35 moles sodium phosphate?
