WebPart 2- The mass of sodium chloride that can react with the same volume of fluorine gas at STP is 62.712g of NaCl. This is because 1 mole of gas occupies 22,4L at STP. Meaning that 1 mole of F2 will also occupy 22.4 L at STP. The next step is to determine the amount of moles F2 will occupy 12L. You do this by first knowing that 22.4L= 1mol. WebStep 1. Write the balanced chemical equation. 4NH₃ (g) + 7O₂ (g) → 4NO₂ (g) + 6H₂O (l) Step 2. Convert mass of NH₃ → moles of NH₃ → moles of NO₂. 100 g NH₃ × 1mol NH3 17.03g NH3 × 4mol NO2 4mol NH3 = 5.872 mol NH₃ (3 significant figures +. 1 guard digit) Step 3. Use the Ideal Gas Law to calculate the volume of NO₂.
How many moles of gas occupy 65.0 L at STP?
WebMay 1, 2016 · (4.5*L)/(22.4*L*mol^-1) xx N_A, where N_A =" Avogadro's number" We assume ideality, and recall that at "STP" 1 mole of ideal gas occupies a volume of 22.4*L. We also know that N_A =" Avogadro's number" = 6.02214xx10^23*mol^-1 So (4.5*L)/(22.4*L*mol^-1) xx 6.02214xx10^23*mol^-1 = "approx. "1/5xxN_A?

WebFluorine. cubic. Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative … WebAug 4, 2024 · Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of 1 mol = 22.4 L is the basis for the conversion factor. Example 10.7. 1: Converting Gas Volume to Moles. Many metals react with acids to produce hydrogen gas. A certain reaction produces 86.5 L of hydrogen gas at STP. WebWhat is the density of helium gas at STP? If the density of the gas is equal to , then FW= 4.00 g/mol, 22.4 L/mol, so the density = 0.179 g/L. dallas craigslist heavy equipment by owner
