If 24 mL of 6.4 M H2SO4 was spilled what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid?
To neutralize sulfuric acid (H₂SO₄), we first need to determine the moles of H₂SO₄ in the spill. The number of moles is calculated as follows: Moles of H₂SO₄ = Volume (L) × Concentration (M) = 0.024 L × 6.4 mol/L = 0.1536 moles. Since sulfuric acid is a strong acid that can donate two protons, it will react with sodium bicarbonate (NaHCO₃) in a 1:2 ratio. Therefore, we need 0.3072 moles of NaHCO₃. The molar mass of NaHCO₃ is approximately 84 g/mol, so the minimum mass required is: Mass = Moles × Molar Mass = 0.3072 moles × 84 g/mol = 25.77 g. Thus, at least 25.77 g of NaHCO₃ should be added to neutralize the spill.
How much carbon dioxide is produced when 3336g of sodium hydrogen carbon breaks down completely?
When sodium hydrogen carbonate (NaHCO₃) decomposes, it produces sodium carbonate (Na₂CO₃), water (H₂O), and carbon dioxide (CO₂). The balanced chemical equation for this reaction is: 2 NaHCO₃ → Na₂CO₃ + H₂O + 2 CO₂. From this equation, 2 moles of NaHCO₃ produce 2 moles of CO₂. Given that the molar mass of NaHCO₃ is approximately 84 g/mol, 3336 g of NaHCO₃ corresponds to 40 moles, which would yield 40 moles of CO₂. Therefore, the total mass of CO₂ produced is about 1,760 g (since CO₂ has a molar mass of about 44 g/mol).
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
Calculate the mass of 0139 moles of copper?
The molar mass of copper (Cu) is 63.55 g/mol. To calculate the mass of 0.139 moles of copper, you can use the formula: mass = moles × molar mass. Therefore, the mass of 0.139 moles of copper is 8.82 grams.
How can one determine the number of moles in a substance using the formula for finding moles?
To determine the number of moles in a substance, you can use the formula: moles mass / molar mass. Simply divide the mass of the substance by its molar mass to find the number of moles.
How can one determine the amount of moles in a given substance?
To determine the amount of moles in a substance, you can use the substance's mass and molar mass. Divide the mass of the substance by its molar mass to calculate the number of moles. This formula is represented as moles mass / molar mass.
Convert grams to moles?
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
How many moles are in 0.525g of AgCl?
To find the number of moles in 0.525g of AgCl, you need to divide the mass by the molar mass of AgCl. The molar mass of AgCl is 143.32 g/mol. moles = mass / molar mass moles = 0.525g / 143.32 g/mol moles ≈ 0.0037 mol
Formula for moles?
number of moles = mass of the material/molar mass
What is the mass in grams of 4.5 moles of carbon?
The mass of 4,5 moles of carbon is 54,04815 g.
What is the mass of 1.23 moles of iron?
The mass of 1.23 moles of iron is 58,69 g.
What is the mass of 0.5 moles of water?
The mass of 0,5 moles of water is 9 g.
