2024年5月31日 · 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 ...

2024年5月24日 · The equivalent weight of Na2SO4 is the molar mass divided by the valency of the ion of interest. For Na2SO4, the molar mass is 142 g/mol and the valency is 2, so the equivalent weight is 71 g/equiv.

2024年5月31日 · You probable think to sodium sulfate, Na2SO4. Na2SO4 has: 7 atoms total - 2 sodium, 1 sulfur and 4 oxygen. 2Na2SO4 (two molecules) have 14 atoms.

2024年5月26日 · Yes, Na2SO4 is a strong electrolyte because it completely dissociates into ions (Na+ and SO4^2-) when dissolved in water, allowing for a high conductivity of electricity. AnswerBot.

2024年5月21日 · Yes, Na2SO4 (sodium sulfate) is an ionic compound. It is composed of sodium ions (Na+) and sulfate ions (SO4^2-), which are held together by ionic bonds formed through the transfer of electrons.

2024年5月31日 · In Na2SO4, there are a total of 3 ions present: 2 Na+ ions and 1 SO4^2- ion. The formula indicates the ratio of ions present in the compound.

2024年6月16日 · In Na2SO4, there are 2 Na+ ions for every 1 Na2SO4 unit. The molar mass of Na2SO4 is 142 g/mol, so in 25 g of Na2SO4, there are about 8.8 g of Na+. What is the name of the polyatomic ion Na2SO4?

2024年10月11日 · 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 ...

2024年6月19日 · In Na2SO4, there are 2 Na+ ions for every 1 Na2SO4 unit. The molar mass of Na2SO4 is 142 g/mol, so in 25 g of Na2SO4, there are about 8.8 g of Na+.

2024年5月29日 · The reaction equation between sodium sulfate (Na2SO4) and water (H2O) is: Na2SO4 + H2O -> 2NaOH + H2SO4. This reaction results in the formation of sodium hydroxide (NaOH) and sulfuric acid (H2SO4).
