Before a chemist can combine a solution with other liquids in a labratory, the temperature of the solution must be between 39c and 52c. the chemist places the solution in a warmer that raises the temperature 6.5c per hour. if the temperature is origionally 0c, how long will it take to raise the temperature to the necessary range of values?

6 hr 6 min

Explanation:

The minimum amount of time necessary is the time it takes to raise the temperature to 39C from 0C (a difference in temperature of 39C). At a rate of 6.4C/hr, the time necessary to change the temperature by 39C is:

(39C) / (6.4C/hr) = 6.09375 hr

Expressed in hours and minutes, this time is 6 hr and 0.09375 hr, or:

(0.09375 hr) ( 60min/hr) = 5.6 minutes

Therefore, at 6 hr and 6 min of heating, the solution will be within the necessary range.
