Answer:
2441.9 Joules
Explanation:
This is a sensible heat change problem.
Energy = Specific Heat Capacity x Mass x Change in Temperature
To find the change in temperature, you need to use this formula: Temperature Final - Temperature Initial.
234.3 - 137.0 = 97.3
Energy = 1.65 x 15.21 x 97.3
Multiply that equation, and you get your answer! I hope this helps!

Explanation:
Hello!
In this case, since the mole fraction relates the moles of solute and the moles of solution, and for sucrose it is:
Whereas we need to compute the moles of both sucrose and water based on their molar masses (342.3 and 18.02 respectively) as shown below:
Thus, the mole fraction sucrose turns out:
Best regards!
Not sure what you need to know, but if it’s true or false it would be false. it’s actually 174.26
Letters A and B are correct because burning fossil fuels can harm the atmosphere through the greenhouse effect and contribute to global warming, and can sometimes spill into the water and harm the environment.
