Want this question answered?
6,35 moles of S contain 38,24059444195.10e23 sulfur atoms.
800 g oxygen are needed.
550 g of nitrogen dioxide is equal to 11,94 moles.
The answer is 64,9 moles.
Sulfur has relative atomic mass of 32 and oxygen have that of 16. The molar mass of sulfur dioxide is 64 grams per mole. Therefore there is approximately 0.58 moles (37.14/64) of sulfur dioxide in given weight.
Four moles of sulfur dioxide would consist of how many molecules?
1.6*avagardo constant Avagardo constant=6.022*10^23
To find the mass of sulfur dioxide (SO₂) that contains the same number of molecules as 2 grams of ammonia (NH₃), you can use the concept of moles and the molar mass. **Find the number of moles of ammonia:** [ \text{Moles of NH₃} = \frac{\text{Mass of NH₃}}{\text{Molar mass of NH₃}} ] The molar mass of ammonia (NH₃) is approximately 17 grams/mol. **Use Avogadro's Number:** According to Avogadro's number, 1 mole of any substance contains the same number of entities (atoms, molecules, etc.), which is approximately (6.022 \times 10^{23}). **Find the number of molecules of ammonia:** [ \text{Number of NH₃ molecules} = \text{Moles of NH₃} \times (6.022 \times 10^{23}) ] **Convert to moles of sulfur dioxide:** Since the number of molecules is the same for both substances, the moles of sulfur dioxide (SO₂) would be the same as the moles of ammonia. [ \text{Moles of SO₂} = \text{Moles of NH₃} ] **Find the mass of sulfur dioxide:** [ \text{Mass of SO₂} = \text{Moles of SO₂} \times \text{Molar mass of SO₂} ] The molar mass of sulfur dioxide (SO₂) is approximately 64 grams/mol. Now, you can substitute the values into the equations to find the mass of sulfur dioxide.
6,35 moles of S contain 38,24059444195.10e23 sulfur atoms.
moles = mass / molar mass assuming that sulfur is simply represented by "S", then the molar mass is 32.07, as seen in the periodic table (meaning that each sulfur atom is 32.07 grams per mole. so moles of sulfur = 80.25 / 32.07 = 2.50 moles
2,22 1023 molecules of carbon dioxide is equal to 0,368 moles.
25 moles of sulfur dioxidecontain 800,825 g oxygen.
3.2 moles
composition stoichiometry.
3.82g of SO2 equals 0,06 moles.
800 g oxygen are needed.
Multiply by avagadro constant. It is equals to 6.022*1^23
