i just need help with question #2

Part 2. One approach to the synthesis of aspirin involves the reaction of salicylic acid with acetyl chloride. This is a very efficient reaction, since the obtained byproduct (Hydrogen chloride) drives the reaction to completion, according to the following chemical equation: H3C OCH3 + HCI Cl O. . How many grams of aspirin can be produced by the reaction of 35.80 g of salicylic acid in the presence of 18.0 2. At the completion of the reaction, water is added to decompose any remaining acetyl chloride, eventually all the mL of acetyl chloride? (The density of acetyl chloride is 1.104 g/mL.) initial acetyl chloride produces HCI. What would be the expected volume in liters of hydrogen chloride gas obtained from the complete decomposition of 10.0 mL of acetyl chloride at 75.3 oF and 758.5 mmig? Assume that no HCl is trapped in the solution. H. HCl

Explanation / Answer

Sol 2 . Volume of acetyl chloride = 10 ml

And , Density of acetyl chloride = 1.104 g/ml

So , mass of acetyl chloride = density × volume = 1.104 × 10 = 11.04 g

Now , molar mass of acetyl chloride = 78.49 g/mol

So , moles of acetyl chloride = mass/molar mass = 11.04/78.49 = 0.14065

As moles of HCl = moles of acetyl chloride = 0.14065

Now , For HCl , PV = nRT

where P = pressure = 758.5 mm Hg = 758.5/760 atm

V = volume

n = moles of gas = 0.14065

R = gas constant = 0.0821 L atm / K mol

T = Temperature = 75.3 °F = 297.2 K

So , V = nRT/P = ( 0.14065 × 0.0821 × 297.2 × 760 )/758.5

= 3.438 L

Therefore , volume of HCl gas obtained is 3.438 L    .
