Figure out how many moles of the titrant (in this case, the base) were needed. Use the balanced chemical equation to calculate the moles of analyte (in this case, the acid) present. Use the volume of analyte to find the concentration of the analyte. Show completed problem To determine the number of moles, we must first determine the molar masses of each of the reactant. CH3COOH: 60.05 g/mol. NaHCO3: 84.01 g/mol. 1mL of vinegar = 0.972 grams = 0.016 moles of vinegar. 1:1 mole ratio between acetic acid and sodium bicarbonate, so 0.016 moles of sodium bicarbonate would react as well.
NaHCO3 + HC2H3O2 -----> CO2 + H2O + NaC2H3O2 This shows us that there should be one mole of acetic acid to one mole of baking soda. The molar mass of acetic acid (HC2H3O2) is about 60 grams per mole, and the molar mass of baking soda (NaHCO3) is about 84 grams per mole.

Nov 28, 2013 · Moles, Molecules, and Grams Lab HP As weve already discussed in class, its easy to make conversions between moles, molecules/formula units, and grams. For example, if we want to go from moles to grams, we use the molar mass to make this conversion. If we want to go from moles to molecules, we use Avogadros number, or 6.02 x 1023.
5. How many moles of NaHCO3 are there in 1/4 tsp of sample? 6. How many moles of CO2 should be produced from the sample? 7. How many moles of CO2 are actually formed? We can predict for the volume by using the ideal gas equation PV=nRT, where P=pressure, V=volume, n=number of moles, R=Ideal gas constant, 0.0821 L-atm/mol-K, T

What's your Point? Like many things in the chemical world, the shape and structure of a molecule is an important determinant of its function. The importance of the bent structure of water is that it provides water with two distinct "sides": One side of the water molecule has two negative lone pairs, while the other side presents the two hydrogens.
2 Lab Safety Today we are working with NaHCO 3 (sodium bicarbonate, also known as baking soda) and 6.0 M HCl. - The baking soda's relatively harmless, but the acid isn't. You'll need a balanced equation, starting moles, and a mole ratio to make some predictions about the end.

For example, the sodium bicarbonate (NaHCO 3) gets broken down into a sodium ion (Na +) and bicarbonate (HCO 3-), while the acetylsalicylic acid breaks down to H + and C 9 H 7 O 4-and the citric acid decomposed to H + and H 2 C 6 H 5 O 7-. In fact, the molecule holding the key to the relief of an Alka-Seltzer® tablet is the bicarbonate ion.
