113 kJ or 113,000J
Explanation:
Since we are condensing it, a physical change in the state of matter is occurring. 113 kJ or 113,000J because of the following equation: Q = 2260 times 50. 2260 is the Heat of Vaporization constant.
Answer:

Explanation:
The given formula is:
[/tex]
In the formula:
T= exposure time
x= carbon monoxide present in ppm
So, to calculate the exposure time when carbon monoxide is 750ppm, you should replace the "x" by 750.
