convert the know heat of fusion of water,334j/g to these units. the conversion between calories and joules is 1 cal = 4.184j

334 J/g x (1 cal/4.184 J) = ? cal/g.

Note how i knew that the factor is 1 ca/4.184 J and not 4.184 J/1 cal. The unit we don't want cancels(J); the unit we want to keep stays(cal).

79.82 cal/g

To convert the heat of fusion of water from joules per gram (J/g) to calories per gram (cal/g), you can use the given conversion factor of 1 cal = 4.184 J.

Here's how you can do the conversion:

1. Start with the given value: Heat of fusion of water = 334 J/g.

2. To convert from joules to calories, divide the value by the conversion factor:

334 J/g ÷ 4.184 J/cal = 79.97 cal/g (rounded to two decimal places).

Therefore, the heat of fusion of water is approximately 79.97 cal/g.
