Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.
Percent concentration, %, is [mass of solute / mass of solution] * 100
Then, if you know the percent and the mass of solution you can find mass of solute as:
mass of solute = % * mass of solution / 100
In this case the solute is bleach.
You have the volume of solution but you need the mass of solution.
The only way to find the mass of solution knowing its volumen is using the density, because density = mass / volume => mass = volume * density.
Then you need the density of the solution, which is not a data.
Then you can find it either experimentally or serching in tables.
I found in Internet that a common density is 1.11 g /ml
Now, we must convert quarts unit to ml, using the conversion factor : 1 quart = 946.35 ml
1 quart * 946.35 ml / quart * 1.11 g/ml = 1050.45 grams of solution
=> grams of solute = 5 * 1050.45 grams / 100 = 52.7 grams of solute
Now use a conversion factor to pass grams to ounes:
1 ounce = 28.35 g
52.7 grams * 1 ounce / 28.35 grams = 1.86 ounces
Answer: 1.86 ounces and I have explainded the method using complete senteces.
