Answer to What is the mass percent of Sodium in Na2SO4?... Question: What Is The Mass Percent Of Sodium In Na2SO4?Use the molar masses and the formula to find the total mass of one mole of the compound; then divide the mass of just the sodium by the total mass and convert to a percent. Na: 2(22.99) = 45.98. S: 32.07.(Na 2 SO 4 ). The molecular formula of sodium sulphate is. Molar mass of = [(2 23.0) + (32.066) + 4 (16.00)] = g Mass percent of an element Mass The balanced reaction of combustion of carbon can be written as: (i) As per the balanced equation, 1 mole of carbon burns in1 mole of dioxygen (air) to...Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a constant composition of elements. The empirical formula is the mole ratio of compounds forming elements. In the same compound, although from different sources...

Molar mass of Na2SO4 | Mass percent

The molecular formula of sodium sulphate is Na2SO4. = 142 g. Mass percent of an element = Mass of that element in the compound / Molar mass of compound x 100.The percent by mass is calculated by atomic mass of element multiply by number of that element in molecule divided by molecular mass of molecule. M(Na₂SO₄) = 142; relative moecular mass of sodium sulfate.Molar mass of Na2 SO4 = 23×2+32+4×16=142. One mole of a mixture of CO and CO2 requires exactly 20 g of NaOH in solution for complete conversion of all the CO2 into Na2 CO3 .8.1 Counting By Weighing 8.2 Atomic Masses: Counting Atoms By Weighing 8.3 The Mole 8.4 Learning To Solve Problems 8.5 Molar Mass 8.6 Percent Composition Of Compounds 8.7 Formulas Of Compounds 8.8 Calculation Of Empirical Formulas 8.9 Calculation Of Molecular Formulas Chapter...Question 2. Calculate the mass percent of different elements present in sodium sulphate (Na2 SO4). Question 6. Calculate the concentration of nitric acid in moles per litre in a sample which has a density 1.41 g mL-1 and the mass percent of nitric acid in it is being 69%.

Well, I don't believe the question has any laborious crack, reason we are discovering the whole composition for the element it self.

Except if you happen to mean; **What is the composition of sodium #(Na)# in sodium sulphate #(Na_2SO_4#

But since its no longer stated, we can to find the entire composition which is in truth #100%# in overall..

#"Sodium sulphate" = Na_2SO_4#

It has the following compositions;

#32.37% = Na#

#22.57% = S#

#45.06% = O#

Or

#32.37% = Na#

#67.63% = SO#

Hence;

#Na_2SO_4 = 100%#
