The relative Atomic Mass of sodium (Na) is 22.990. You can find the atomic mass of any element by looking on the Periodic Table of the elements. Sodium is located on the first column, left hand side.
To determine the number of moles of sodium carbonate in 2 grams of hydrated sodium carbonate, we first need to calculate the molar mass of Na2CO3·xH2O. Once we have the molar mass, we can use the formula: Moles = Mass / Molar mass. Given that hydrated sodium carbonate has the molar mass of Na2CO3·xH2O, we can determine the number of moles in 2 grams of the compound.
108.2/ molar mass of sodium oxide =108.2/62 =1.75 1.75 x 2 (because there are 2 Na's in the fomular of sodium oxide) =3.5 3.5 x the molar mass of sodium =3.5 x 23 =80.3 grams
To find the number of moles of sodium sulfate in 0.1000g of the compound, you first need to determine the molar mass of Na2SO4. Then, divide the given mass by the molar mass to get the moles.
To find the number of moles in 2.12g of sodium carbonate, you first need to determine the molar mass of Na2CO3 (105.99 g/mol). Then, divide the given mass by the molar mass to get the number of moles. In this case, 2.12g / 105.99 g/mol ≈ 0.02 moles of sodium carbonate.
To calculate the number of moles of sodium carbonate in 212g, you need to first determine the molar mass of Na2CO3 (sodium carbonate). The molar mass of Na2CO3 is 105.99 g/mol. Then, you divide the given mass (212g) by the molar mass to find the number of moles (212g / 105.99 g/mol = 1.999 moles).
Look at a Periodic Table.
the atomic mass
To determine the number of moles in 4g of sodium, you need to divide the given mass by the molar mass of sodium. The molar mass of sodium is 22.99 g/mol. Therefore, 4g of sodium is equal to 0.174 moles.
To determine the number of moles of sodium carbonate in 2 grams of hydrated sodium carbonate, we first need to calculate the molar mass of Na2CO3·xH2O. Once we have the molar mass, we can use the formula: Moles = Mass / Molar mass. Given that hydrated sodium carbonate has the molar mass of Na2CO3·xH2O, we can determine the number of moles in 2 grams of the compound.
The molar mass of sodium chloride is 58.44 g/mol. To find the mass of sodium chloride formed, you need to compare the moles of sodium and chlorine to determine the limiting reactant. Calculate moles of sodium and chlorine, determine limiting reactant, and use stoichiometry to find mass of sodium chloride formed.
To calculate the mass of sodium chloride produced, first balance the chemical equation for the reaction between sodium oxide and calcium chloride. Next, determine the molar ratio between sodium oxide and sodium chloride in the balanced equation. Finally, use the given mass of sodium oxide and the molar mass of sodium chloride to calculate the mass of sodium chloride produced.
108.2/ molar mass of sodium oxide =108.2/62 =1.75 1.75 x 2 (because there are 2 Na's in the fomular of sodium oxide) =3.5 3.5 x the molar mass of sodium =3.5 x 23 =80.3 grams
To find the number of moles of sodium sulfate in 0.1000g of the compound, you first need to determine the molar mass of Na2SO4. Then, divide the given mass by the molar mass to get the moles.
The chemical formula for sodium oxide is Na2O. To determine the mass percent of oxygen in Na2O, we need to calculate the molar mass of oxygen (O) and sodium oxide (Na2O), then use these values to calculate the mass percent of oxygen in Na2O.
the mass number of sodium is 23
23. Sodium (Na) has 11 electrons (it's atomic number) and so must have 11 protons, add in a neutron for good measure and we get 23. The atomic weight (not mass) of sodium is 22,989 769 28(2).
there is no such thing as an average mass of a sodium. sodium is an element. a sodium molecule's mass will therefore be exact in mass, never average.
