The balanced equation is given as:
CaCO3 (s) + 2HCl (aq) ---> CO2 (g) + H2O (l) + CaCl2 (aq)
To calculate the amount of CO2 gas produced in this reaction, we follow certain steps:
Step 1: Calculation of No. of moles of HCl
The number of moles of HCl will be = (10.0/1000) L X 0.300 M = 0.003 mole [M = mole/L]
(Since, Molarity = No. of moles of solute / Volume of solution in liters)
Step 2: Calculation of moles of CO2 from moles of HCl using the balanced chemical equation
2 moles of HCl produces = 1 mole of CO2
Hence, 0.003 mole of HCl will produce = (1/2) X 0.003 mole = 1.5 X 10-3 mole of CO2
Step 3: Convert the number of moles of CO2 to grams of CO2
Grams of CO2 gas produced are = 1.5 X 10-3 mole X 44 g/mol [Molar mass of CO2 = 44 g/mol]
= 0.0660 g
(Since, Grams of gas produced = No. of moles of gas X Molar mass of gas)
Therefore, 0.0060 g of CO2 gas are produced in this reaction.
