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.

I was wondering about this... but I think if you combined..The four oxygen gas O2, and the two of Hydrogen gas H2.. and predict was will happened I guess this is what it will or might be calculate, but Im not sure.KKKO2O2+H2H1O4+H2O2H
How many atoms of sulfur are present in 155 g of sulfur?
To determine the number of sulfur atoms in 155 g of sulfur, you first need to calculate the number of moles of sulfur present. The molar mass of sulfur is approximately 32.06 g/mol. By dividing the given mass by the molar mass, you find that there are approximately 4.83 moles of sulfur. Since one mole of sulfur contains Avogadro's number of atoms (6.022 x 10^23), you can calculate that there are approximately 2.91 x 10^24 sulfur atoms in 155 g of sulfur.
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.

How many moles of O atoms are present in a 254g sample of carbon dioxide?
To find the number of moles of oxygen atoms in a 254 g sample of carbon dioxide (CO₂), first calculate the molar mass of CO₂, which is approximately 44 g/mol (12 g/mol for carbon and 32 g/mol for two oxygen atoms). The number of moles of CO₂ in the sample is 254 g ÷ 44 g/mol = about 5.77 moles. Since each molecule of CO₂ contains two oxygen atoms, the total number of moles of oxygen atoms is 5.77 moles × 2 = approximately 11.54 moles of O atoms.
How many atoms are in 64 g sulfur?
2(6.02 x 10^23) atoms
How many grams atoms are in 100 of sulfur?
The molar mass of sulfur is approximately 32 grams per mole. Therefore, 100 grams of sulfur would contain approximately 3 moles of sulfur atoms (100 grams / 32 grams/mole). To find the number of atoms, you would then multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mole) to get the total number of sulfur atoms in 100 grams.
How many grams of sodium sulfate will be formed if you start with 200grams of sodium hydroxide and you have an excess of sulfuric acid?
First write down the BALANCED reaction equation. 2NaOH + H2SO4 = Na2SO4 + 2H2O Note the molar ratios are 2:1::1:2 So two moles of NaOH produces one mole of Na2SO4 Next calculate tghe moles of NaOH mol(NaOH) = 200/(23 + 16 + 1) = 200/40 = 5 mol(NaOH) = 5 (This figure is equivalent to '2' above) mol(Na2SO4) = 5/2 = 2.5 ( Equivalent to '1' above) mol(Na2SO4) ; 2.5 = mass(g) / (2 x 23) + 32 + (4 x 16)) 2.5 = mass(g) / 142) mass*Na2SO4) = 2.5 x 142 = 355 g
How many hydrogen atoms in 2 moles of hydrochloric acid?
In 2 moles of hydrochloric acid (HCl), there are 2 moles of hydrogen atoms. Since each molecule of HCl contains one hydrogen atom, multiplying the moles of HCl by Avogadro's number (6.022 x 10^23) gives the number of hydrogen atoms. Therefore, there are 1.204 x 10^24 hydrogen atoms in 2 moles of HCl.
How many atoms are present in 8g of S?
To determine the number of atoms in 8g of sulfur (S), you would first calculate the number of moles using the molar mass of sulfur (32 g/mol). Then, using Avogadro's number (6.022 x 10^23), you can convert the moles to atoms.
What mass of Na2SO4 is needed to make 2.5L of a 2M solution?
In 1 litre (L) there are 2 moles (M) So in 2.5 L you have 2.5 X 2 = 5 moles. Remember the moles eq'n moles = mass(g) / Mr Hence mass(g) = moles X Mr Next refer to the Periodic Table in order to find the atomic masses of the atoms in sodium sulphate (Na2SO4) Na x 2 = 23 X 2 =46 S x 1 = 32 X 1 = 32 O x 4 = 16 X 4 = 64 46 + 32 + 64 = 142 ( The Mr of sodium sulphate). Substituting into the equation mass(g) = 5 moles X 142(Mr) mass(g) = 710 g is required. To make at a practical level. have approximately 1.5 litres of water . dissolve the whole mass of sodium sulphate (710 g) in this quantity of water. You will notice that the volume of the solution increases. Then add sufficient water to make a total volume of 2.5 litres. NB Do NOT add the sodium sulphate to 2.5 litres. Because then you will have more volume of less molarity .
