I need to calculate the mass of CO2 produced in the reaction of NaHCO3 + HCl
Data
Mass of NaHCO3 = .05g
Mass of system before reaction 117.9 g
Mass of system after reaction 117l98
Maxium pressure 1.4094
initial pressure 1.0094
pressure change .4
temp 299.2K
No idea what the set up was.
max P = 1.4094 what?
initial P = what unit?
atmosphere probably.
Did the system gain weight? If so due to what?
To calculate the mass of CO2 produced in the reaction, you can use the concept of stoichiometry and the Ideal Gas Law.
1. Determine the balanced chemical equation for the reaction:
NaHCO3 + HCl → NaCl + CO2 + H2O
This means that for every 1 mole of NaHCO3 reacted, 1 mole of CO2 is produced.
2. Calculate the number of moles of NaHCO3 used in the reaction:
Given that the mass of NaHCO3 is 0.05g and the molar mass of NaHCO3 is 84 g/mol, you can use the formula:
Number of moles = Mass / Molar mass
Number of moles of NaHCO3 = 0.05g / 84 g/mol
3. Calculate the number of moles of CO2 produced:
Since the stoichiometry of the reaction is 1:1 between NaHCO3 and CO2, the number of moles of CO2 produced is also 0.05g / 84 g/mol.
4. Calculate the mass of CO2 produced:
Using the molar mass of CO2 (44 g/mol), you can calculate the mass of CO2 produced by multiplying the number of moles by the molar mass:
Mass of CO2 = Number of moles of CO2 * Molar mass of CO2
However, the given data you provided does not include any information directly related to the mass of CO2 produced. The data you provided consists of the mass of NaHCO3, mass of the system before and after the reaction, pressure information, and temperature.
To calculate the mass of CO2 produced, you would need additional information such as the volume of the reaction vessel or the pressure change during the reaction.
