2xNa => 46u Atomic Mass
1x(SO4) => 96u atomic mass
tot = 142u
4.5g/142u = 0.03169014085g/u
Ans x 96u = 3.04g = 3.0g of SO4
To determine the mass of SO4 ions in 4.5g of Na2SO4, first calculate the molar mass of Na2SO4 (which is 142.04 g/mol). Next, find the molar mass ratio of SO4 in Na2SO4 (which is 96.06 g/mol out of 142.04 g/mol). Finally, calculate the mass of SO4 ions by multiplying the molar mass ratio by the total mass of Na2SO4 (4.5g).

How many grams of Na+are contained in 25 g of sodium sulfate (Na2SO4)?
To find the mass of Na+ in sodium sulfate (Na2SO4), we need to consider the molar ratios of Na+ in the compound. 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 device used to determine atomic masses?
A mass spectrometer is a device used to determine atomic masses by separating and measuring the mass-to-charge ratio of ions. By analyzing the deflection of ions in a magnetic or electric field, the mass spectrometer can provide accurate measurements of atomic masses.
How many moles of sodium sulfate are in 0.1000g of the compound?
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.
How many moles of ammonium ions are in 6.955?
To determine the number of moles, you need to know the molar mass of ammonium ions, NH₄⁺. The molar mass is 18.038 g/mol. You can then divide the given mass (6.955 g) by the molar mass to find the number of moles.
How many moles of ammonium ions does a 22.5 gram sample of ammonium carbonate?
To calculate the number of moles of ammonium ions in a 22.5 gram sample of ammonium carbonate, you need to first determine the molar mass of ammonium carbonate. Then, divide the given mass by the molar mass to find the number of moles. After that, since there are 2 ammonium ions in one molecule of ammonium carbonate, you will need to multiply the result by 2 to determine the number of moles of ammonium ions.
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.
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.
What instrument would be best to determine how different oxidation states affect the mass of a carbon based compound?
Mass spectrometry would be the best instrument to determine how different oxidation states affect the mass of a carbon based compound. Mass spectrometry is capable of accurately measuring the mass-to-charge ratio of ions, allowing for the identification of the compound and its various oxidation states based on their mass differences.

What deflects the ions?
Instruments like ion optics or electrode systems are commonly used to deflect ions in mass spectrometry. These systems apply electric or magnetic fields to manipulate the ions' trajectories, allowing for separation, focusing, or redirection of the ions. The specific design and configuration of these components determine how effectively ions can be deflected based on their mass-to-charge ratios.
