Question

How many joules of heat are needed to completely vaporize  of water at its boiling point? Given  = 40.6 kJ/mol

Quizplus · Accepted Answer

First, we need to calculate the amount of energy required to vaporize one mole of water:
40.6 kJ/mol / 1000 J/kJ = 40,600 J/mol

Now we can calculate the energy required to vaporize the given amount of water:
11ea71d6_78b7_4d38_91e5_b9203607f431_TB6110_11 x 40,600 J/mol = 457,940 J

Therefore, the answer is B, 11ea71d6_78b7_4d3a_91e5_8f02b4f8e9c5_TB6110_11.
