Question

Otto 2/4 Ahvap = 0.6761078-5.0/CX 183.213/17.91 = 33.13 1288°C] b. How much energy must be removed to convert all 17.9 g of liquid acetic acid to solid acetic acid, assuming the acid is already at the freezing point of 10.01 See data sheet for helpful values (2 points) At mett-Att f = 0.185273kJ/9 IT freeze 0.185273x Isoroc/17.99 = 0.16570000000 1/2

Answer 1

Step-by-step explanation:

It is given that mass of acetic acid is 17.9 g and freezing point is given as
`10.01^(o)C`.

For acetic acid,
`\Delta H_(f)` = 0.185273 kJ/g

Therefore, total heat removed to convert 17.9 g of acetic acid from liquid to solid is as follows.

Q =
`m * \Delta H_(f)`

=
`17.9 g * 0.185273 kJ/g`

= 3.316386 kJ

Thus, we can conclude that 3.316386 kJ energy must be removed to convert all 17.9 g of liquid acetic acid to solid acetic acid.
