The amount of KNO₃ precipitated out of solution when you cooled the solution from 100°C to -22°C is obtained from the solubility curve
<h3>What is a solubility curve?</h3>
A solubility curve is a curve of the solubility of a solute against temperature.
The solubility curve shows that the solubility of different solute at different temperatures.
The solubility curve of KNO₃ is as shown. Solubility at 100 °C and -22 °C is not shown in the curve.
However, the amount of KNO₃ precipitated out of solution when cooled the solution from 100 °C to -22 °C can be determined by subtracting the amount of solute dissolve at -22 °C from that dissolved at 100 °C.
In conclusion, the solubility curve is used to determined the amount of solute dissolved in a given volume of solvent at different temperatures.

#SPJ1
=58.464 kg/hr
width= 21.0 feet
length= 20.0 feet
snowflake mass=1.60 milligrams
1 foot^2=1450 snowflakes per minute
area of lawn=length*width
area=(21.0)(20.0)
area=420 feet^2
1450 snowflakes at 1.60 milligrams per snowflake:
(1.60)(1450)=2320 milligrams
2320 milligrams to kilograms:
=(2320 mg)(1 gram/1000 mg)(1 kilogram/1000 grams)
=(2320)(1/1000)(1/1000)
=(2.32)(1/1000)
=0.00232 kg per minute
0.00232 kg per minute to kg per hour:
=(0.00232 kg/1 minute)(60 minutes/1 hour)
=(0.00232)(60)
=0.1392 kg per hour per square foot
For the total lawn's accumulation in kilograms per hour, multiply by area:
=(0.1392 (kg/hr) per 1 foot^2)(420 feet^2)
=58.464 kilograms of snow accumulate on the lawn per hour
Answer:
D. Ten apples cost $9
Explanation:
C, the cost in dollars of buying apples is a function of the number (n) of apples bought
C (10) = $9 implies that the cost of buying 10 apples is $9
