Answer 1

lf. a mass of sodium carbonate = mass of Nag CO₂, H2O and test tube - mass of test tube = 45.491-43.628 - 1.8639 11.869 Rounded ans. . 1g. a moles of sodium carbonate = mass of Na2CO3. 120 moler mass = 16.015 moles] moles = 1.86 124 - This mass of Nach = mass of test tube and Nach - mass of test tube = 45.718 - H3.628 = - li» moles of Nace = mass of NaCl = 2.09 1 molar mass 58.5 = 10.0357) – 10.036 experimental molar ratio = moles of Nall moles of Na₂CO3-H2O - lý - 0.025 = 24

ki a pevotune Temperature of carbon dioxide will be same as of reaction mixture and equal to 213 +25. H = 1298.4K) is 11. = pressure of coz in atm = 769.11 atm 760 = 1.0119 atm Ima moles of coz a moles of Na2CO3. H₂O = 10.015] 015 In. a volume of coouh = HRT 10.364) = 0.015X 0.0821x298.4 1.0119 I have done you can do calculation for for bicarbonate carbonate , similanly bart.
