How many Na2SO4 molecules are present in 1.125 moles?
1,125 moles of sodium sulfate contain 6,774908464125.10e23 molecules.
How do you determine the number of moles in an element?
Multiply the # of grams by the element's atomic weight. Or if dealing with milliliters, multiply the volume by solutions molarity. When calculating a molecule's # of moles, multiply the # of grams by the molecular weight.
How many moles of Na SO4 are in 25.0 of this compound?
To find the number of moles of Na2SO4 in 25.0 g of the compound, you need to convert the mass to moles. First, determine the molar mass of Na2SO4, then divide the given mass by the molar mass to obtain the number of moles.
How much na2so4 is obtained when 4.00g of h2so4 reacts with 4.00g of naoh?
The balanced chemical equation for the reaction is: H2SO4 + 2NaOH -> Na2SO4 + 2H2O. To find the amount of Na2SO4 produced, first find the limiting reactant by calculating the moles of each reactant. Then, use the mole ratio from the balanced equation to determine the moles of Na2SO4 produced. Finally, convert moles to grams using the molar mass of Na2SO4 to find the final amount.
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 in 5.25 mole of Na2SO4?
There are 10.5 moles of sodium in 5.25 moles of Na2SO4 because there are 2 sodium atoms in one formula unit of Na2SO4.

How many moles are in Na2SO4?
To determine the number of moles in Na2SO4, you first need to know the molar mass of the compound. The molar mass of Na2SO4 (sodium sulfate) is calculated by adding the atomic masses of each element present: 2(Na) + 1(S) + 4(O) = 2(22.99 g/mol) + 1(32.07 g/mol) + 4(16.00 g/mol) = 142.04 g/mol. To find the number of moles, you divide the given mass of Na2SO4 by its molar mass.
What is the molality of a solution containing 10.0g of Na2SO4 dissolved in 1000.0g of water?
To find the molality, we first calculate the moles of Na2SO4: 10.0g Na2SO4 * (1 mol Na2SO4 / 142.04g Na2SO4) = 0.0705 moles Na2SO4. Then, molality is calculated as moles of solute (Na2SO4) / kilograms of solvent (water): 0.0705 mol / 1.000 kg = 0.0705 mol/kg, which is the molality of the solution.
How many atoms are in 3.2 moles of Na2SO4?
There are approximately (1.93 \times 10^{24}) atoms in 3.2 moles of Na2SO4. This value is calculated using Avogadro's number (6.022 x 10^23 atoms/mol) and the formula weight of Na2SO4.
How many ml of 0.24M of Na2so4 will be oxidised by 180 ml of 0.32 kmno4 in acid medium?
To find the volume of 0.24M Na2SO4 oxidized by 0.32 kmno4, first calculate the number of moles of KMnO4 using the formula M1V1 = M2V2. Then, use the mole ratio between KMnO4 and Na2SO4 (from the balanced equation) to find the moles of Na2SO4 oxidized. Finally, convert the moles of Na2SO4 to volume using its molarity.
How many moles of atoms are contained in 2.88g na2 so4?
Full formal set up. 2.88 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(6.022 X 1023/1 mole Na2SO4)(1 mole Na2SO4 atoms/6.022 X 1023) = 0.020 moles of sodium sulfate atoms ------------------------------------------------------( you can see the last two steps are superfluous )
How many grams of sodium are in 0.820 moles of Na2SO4?
To find the grams of sodium in 0.820 moles of Na2SO4, first calculate the molar mass of Na2SO4: 2(Na) + 1(S) + 4(O) = 2(23) + 32 + 4(16) = 142 g/mol. Since each mole of Na2SO4 contains 2 moles of Na atoms, the molar mass of Na in Na2SO4 is 46 g/mol. Therefore, in 0.820 moles of Na2SO4, there are 0.820 moles * 2 moles Na * 46 g/mol = 75.32 grams of sodium.
