Answer #1

Part 1.

a. Moles of Na2CO3 = 0.1 g/(106 g/mol) = 9.434*10-6 mol

According to the following equation: Na2CO3 --\Delta--> Na2O + CO2(g)

The mole ratio Na2CO3:CO2 = 1:1

Therefore, the moles of CO2 produced = 9.434*10-6 mol

b. Na2CO3 + 2HCl ----> 2NaCl + CO2 + H2O

The mole ratio HCl:CO2 = 2:1

The moles of HCl = (5/1000) L * 1 mol/L = 0.005 mol

Therefore, the moles of CO2 produced = 0.005/2 = 0.0025 mol

c. According to ideal gas equation:

PV = nRT

i.e. P * (300/1000) L =  9.434*10-6 mol * 0.0821 L.atm/mol.K * (21.5+273) K

Therefore, the pressure of CO2 (P) = 7.6*10-4 atm
