Question

Which best represents the units of the average rate of change for the boiling point based on the amounts of ethylene glycol in the 100ml solutions?

a. 1/(mililiters*degrees Fahrenheit)

b. degrees Fahrenheit/(mililiters)

c. (mililiters)/degrees Fahrenheit

d. (mililiters*degrees Fahrenheit)/1

Answer 1

Option b. degrees Fahrenheit/(mililiters)

Explanation:

we know that

The formula to calculate the average rate of change between two points is equal to

`m=(y2-y1)/(x2-x1)`

we have that

the units of the y-axis are
`{\°F}`

the units of the x-axis are
`{ml}`

therefore

the units of the the average rate of change are

`m=(\°F)/(ml)`
