For every one molecule of NaHCO3(s) there is one molecule of CO2(g) that forms: NaHCO3(s) + CH3CO2H(aq) --> CO2(g) + H2O(l) + NaCH3CO2(aq) This means that if we know how many moles of gas we need, we need the same number of moles of sodium bicarbonate to produce it. Now, we need something to fill with gas. I'll be filling a 1-quart sealable plastic bag. 1 quart is 946 mL (0.946 L). We can use the ideal gas law to determine how much gas (in moles) is needed to fill 946 mL. Remember there are four variables for the ideal gas law. Ideal Gas Law: PV = nRT P = pressure: typically 715 mm Hg in Spokane <-- unit dictates which R to use V = volume: 1 quart bag = 0.946 L <-- must be in Liters T = room temperature: 20 °C in my lab, +273 = 293 K <-- must be Kelvin n = moles: what we are solving for I used atmospheric pressure in mm Hg, so I'll have to pick the R value with "mm Hg" in the units: R = 62.4 L × m m H g K × m o l Now, use these values to calculate how many moles of…
A 0.2088 g sample of primary-standard-grade sodium carbonate, Na₂CO₃ (105.99 g/mol) was dissolved in water and diluted to 100.00 mL in a volumetric flask. A 30.00-mL portion of this solution was used to standardize a hydrochloric acid (HCl) solution based on the following reaction: CO₃²⁻ + 2H⁺ → H₂O + CO₂. If 36.09 mL of the HCl solution was used to reach the end point, what is the molarity of the HCl?
Based on the molar ratio in the balanced chemical reaction equation, how many moles of NaOH is present in question 8? Question 8= If 20.00 mL (0.0200 L) of the oxalic acid solution prepared in question 6 is used to titrate a NaOH solution, how many moles of H2C2O4 is used? 1.5234 grams of H2C2O4·2H2O is dissolved in water to prepare a 0.250 L solution
