What mass of sodium carbonate must be used to produce 10.36L of carbon dioxideat 24°C and 103kPa aaccording to neutralization reaction.
To calculate the mass of sodium carbonate required to produce carbon dioxide (CO2) according to a neutralization reaction, we need to know the balanced chemical equation and the molar ratio between sodium carbonate and CO2. Unfortunately, the exact reaction is not provided.
However, let's assume the reaction follows a typical neutralization reaction, where sodium carbonate (Na2CO3) reacts with an acid (HCl) to produce water (H2O), carbon dioxide (CO2), and the corresponding salt (NaCl):
Na2CO3 + 2 HCl → H2O + CO2 + 2 NaCl
From this equation, we can see that 1 mole of sodium carbonate (Na2CO3) yields 1 mole of carbon dioxide (CO2).
Now, to calculate the mass of sodium carbonate required, we need to follow these steps:
Step 1: Determine the molar volume of gas at the given conditions.
The ideal gas equation can be used to calculate the molar volume of carbon dioxide at the given temperature and pressure.
PV = nRT
V = volume of gas = 10.36 L
T = temperature = 24°C = 297 K (convert Celsius to Kelvin)
P = pressure = 103 kPa
R = ideal gas constant = 8.31 J/(mol·K)
Rearranging the equation, we get:
n = PV / RT
Substitute the known values:
n = (103 kPa * 10.36 L) / (8.31 J/(mol·K) * 297 K)
n ≈ 4.12 mol
Step 2: Calculate the mass of sodium carbonate.
Since the mole ratio between Na2CO3 and CO2 is 1:1, the number of moles of Na2CO3 required will be the same as the number of moles of CO2 produced. Therefore, we need 4.12 moles of Na2CO3.
To calculate the mass, you'll need the molar mass of Na2CO3, which is:
Na = 22.99 g/mol
C = 12.01 g/mol
O = 16.00 g/mol (x3, as there are three oxygen atoms in the carbonate ion)
The molar mass of Na2CO3 is:
(22.99 g/mol * 2) + 12.01 g/mol + (16.00 g/mol * 3) = 105.99 g/mol
Now, multiply the number of moles by the molar mass:
Mass of Na2CO3 = 4.12 mol * 105.99 g/mol
Mass of Na2CO3 ≈ 437 g
Therefore, approximately 437 grams of sodium carbonate must be used to produce 10.36 L of carbon dioxide at 24°C and 103 kPa according to a neutralization reaction. Note that the specific reaction and balanced equation may differ, so this calculation assumes a generic neutralization reaction.
To calculate the mass of sodium carbonate required to produce a given volume of carbon dioxide, we first need to know the balanced equation for the neutralization reaction.
Since you mentioned a neutralization reaction, let's assume that the reaction is between sodium carbonate (Na2CO3) and an acid, which produces carbon dioxide (CO2) as one of the products.
The balanced equation for this reaction is:
Na2CO3 + 2HCl → 2NaCl + CO2 + H2O
Now, let's determine the number of moles of carbon dioxide required to fill 10.36L at 24°C and 103kPa (which is essentially atmospheric pressure).
We'll use the ideal gas law equation, PV = nRT, where:
P = pressure (in Pa)
V = volume (in m3)
n = number of moles
R = ideal gas constant (8.314 J/(mol·K))
T = temperature (in Kelvin)
First, let's convert the given conditions into Kelvin and moles:
Temperature (T) = 24°C + 273.15 = 297.15 K
Pressure (P) = 103 kPa = 103,000 Pa
Using the ideal gas law equation, we can rearrange it to solve for the number of moles (n):
n = PV / RT
n = (103,000 Pa) * (10.36 L) / (8.314 J/(mol·K) * 297.15 K)
Note: Make sure to convert the volume from liters to cubic meters by multiplying by 0.001.
Calculating the value, n, will give us the number of moles of carbon dioxide required.
Now, looking at the balanced equation, the mole ratio between carbon dioxide and sodium carbonate is 1:1. This means that 1 mole of carbon dioxide corresponds to 1 mole of sodium carbonate.
Therefore, the mass of sodium carbonate required can be calculated since the molar mass of sodium carbonate (Na2CO3) is approximately 105.99 g/mol.
Mass of sodium carbonate = number of moles * molar mass
Now, substituting the calculated number of moles into the equation:
Mass of sodium carbonate = n * molar mass
Finally, to calculate the mass of sodium carbonate required to produce the given volume of carbon dioxide, plug in the calculated values into the mass equation.
Please note that we are assuming an ideal scenario here; in a real lab, reaction efficiency may vary.
