Title: How do you calculate the moles of a solution that is not given in the equation? Post by: tony12 on Feb 15, 2013 The mass of carbon dioxide produced from run "A" is 0.055 g. Based on the balanced equation:
HCO3?(aq) + H+(aq) H2O(l)+CO2(g) What is the number of moles of the reacted sodium bicarbonate from the single Alka Seltzer tablet? Title: How do you calculate the moles of a solution that is not given in the equation? Post by: michdem on Feb 15, 2013 According to the equation, you are supposed to get 1 mol or 44g of carbon dioxide if you started with one mole of sodium bicarbonate.
Since you only got 0.55g of CO2, you have .55/44 = 0.0125 mol. Therefore, you started off with 0.0125 mol sodium carbonate. |
