A sample of vinegar was found to have an acetic acid concentration of 0.8846 m. What is the acetic acid % by mass? Assume the de
jenyasd209 [6]

Answer:

5.3%

Explanation:

Let the volume be 1 L

volume , V = 1 L

use:

number of mol,

n = Molarity * Volume

= 0.8846*1

= 0.8846 mol

Molar mass of CH3COOH,

MM = 2*MM(C) + 4*MM(H) + 2*MM(O)

= 2*12.01 + 4*1.008 + 2*16.0

= 60.052 g/mol

use:

mass of CH3COOH,

m = number of mol * molar mass

= 0.8846 mol * 60.05 g/mol

= 53.12 g

volume of solution = 1 L = 1000 mL

density of solution = 1.00 g/mL

Use:

mass of solution = density * volume

= 1.00 g/mL * 1000 mL

= 1000 g

Now use:

mass % of acetic acid = mass of acetic acid * 100 / mass of solution

= 53.12 * 100 / 1000

= 5.312 %

≅ 5.3%

Michigan v. Tyler was the Supreme court ruling that they violated when

warrantless search was done.

<h3>Michigan v. Tyler case</h3>

The Court of Appeals of the State of Michigan affirmed the conviction for the

exception of a warrantless search only in the case of an arson.

In this case, there was no arson involved which is against the rule of law as

various items (stolen money, illegal weapons, drugs) were only searched for.

This thereby violates the U.S. Supreme Court ruling between Michigan v.

Tyler.
