Sure, here are the steps to calculate the volume of carbon dioxide formed:

1. Determine the mass of one mole of NaHCO3: The molar mass of NaHCO3 (Sodium bicarbonate) is calculated as follows: Na = 23 g/mol, H = 1 g/mol, C = 12 g/mol, O = 16 g/mol, and there are 3 O atoms. So, the molar mass of NaHCO3 = 23 + 1 + 12 + (3*16) = 84 g/mol.

2. Calculate the number of moles of NaHCO3 used: The number of moles is calculated by dividing the mass of the substance by its molar mass. So, the number of moles of NaHCO3 = 12.6 g / 84 g/mol = 0.15 mol.

3. Determine the number of moles of carbon dioxide formed: The balanced chemical equation for the reaction is: 2NaHCO3 -> Na2CO3 + H2O + CO2. From this equation, we can see that 2 moles of NaHCO3 produce 1 mole of CO2. So, the number of moles of CO2 = 0.15 mol / 2 = 0.075 mol.

4. Calculate the volume of carbon dioxide formed at room temperature and pressure: At room temperature and pressure (RTP), 1 mole of any gas occupies 24 liters. So, the volume of CO2 = 0.075 mol * 24 L/mol = 1.8 L.

Therefore, the volume of carbon dioxide formed at room temperature and pressure when 12.6g of NaHCO3 is heated is 1.8 liters.
