Question

this is the data I have now

Jerome Name: Cathia Lab Partner: Chem 105/110 Section: Experiment Date: Mole Ratios and Reaction Stoichiometry Reaction A: Sodium Bicarbonate and Hydrochloric Acid Experimental Data (a) Mass of evaporating dish + watch glass (b) Mass of evaporating dish + watch glass + sodium bicarbonate (c) Mass of sodium bicarbonate used (d) Mass of evaporating dish + watch glass + sodium chloride (e) Mass of sodium chloride collected (experimental yield) 73.289 75.799 2249 .63 Data Analysis 1) Use your data to determine the experimental mole-to-mole ratio between sodium bicarbonate and sodium chloride. Show your work for each step. • Convert the mass of sodium bicarbonate used to moles. • Convert the mass of sodium chloride collected to moles. Divide both of your results from the preceding two steps by the lower mole value to determine the simplest mole-to-mole ratio between sodium bicarbonate and sodium chloride. Simplest mole ratio before rounding moles NaHCO, moles Naci Simplest whole number mole ratio after rounding moles NaHCO, : moles NaCl

Answer 1

now mass of sodium bicarbonate = mast of evopeting doch + watch glass + map of NaHCO3 84.0079) not (morsy evapshing bosh + watehghest 75.789 - 73.28g mase of NaHCO3 = 2.59 Convert mass of Nathcoz to mokes Imole of NaHCO = 84.007 g/mol. for 2.59 of Natioz =) nogmoles - 2.58 Inde = 0.02975 moles. now 18 mass of Sodium cheide - (Monty 1.639 Convent mast of Nach to moles. Imole of NaCl = 58.449/mot. fh 1.639 & Nac! - nog moes = 1.639 & Imole S8.uy = 0.02 789 metel now the moles of wach is less than moles of valt Coz fch mole ratio of Natco - 0.02975 - 1.06669 moles of 0.02789 – 22:4 toh more latio of Nac! - 0.02709 = Inole of wach 0.02789 wat Con & I mole of Nael. o mole latio beldle dounding 1.06669 moles of Nahco male latio after founding sound tolplace lol moles & NaHCO & Imole of Nach
