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

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+.
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.
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 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.
What is the mass in grams of 0.150 mol of sodium sulfate?
To find the mass of sodium sulfate, we need to know the molar mass of Na2SO4, which is about 142.04 g/mol. Multiply the number of moles by the molar mass to get the mass: 0.150 mol * 142.04 g/mol = 21.31 grams. So, the mass of 0.150 mol of sodium sulfate is 21.31 grams.
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.
