ALL THREE QUESTIONS PLS$,$ Will upvote!!!A Question $16(1$ point$)$ Retake question

How much heat $($in $kJ)$ is required to convert $111g$ of liquid water at $100\mathrm{.}0C$ into

water vapor and increase that temperature to $119C?$

Hint: You will need two equations that you add together because the water is a

liquid.

Tip $1$: One equation uses $m$ and the other uses $n.n$ is moles. $m$ is mass in grams.

You should put the final units for both in terms of grams.

Tip $2$: One equation will come out in J$.$ One will come out in $kJ.$ You have to put

them both in $kJ$ before you can add them.

Values that may be needed for this problem.

$Hvap(H_{2}O,100C)=43\mathrm{.}9k\frac{J}{m}ol$

$$ Hfus $(H_{2}O,0C)=6\mathrm{.}02k\frac{J}{m}ol$

$c_{\text{i}\text{c}\text{e}}=2\mathrm{.}09\frac{J}{g^{**}C}$

$c_{\text{w}\text{a}\text{t}\text{e}\text{r}}=4\mathrm{.}184\frac{J}{g^{**}C}$

$c_{\text{v}\text{a}\text{p}}(H_{2}O)=1\mathrm{.}84\frac{J}{g^{**}C}$

Your answer should be rounded to the ones position for this answer.

How much heat $($in $kJ)$ is required to convert $111g$ of solid water at $-31C$ into liquid

water at $0C.$

Hint: You will need two equations that you add together because the water is a

liquid.

A Question $18(1$ point$)$ Retake question

How much heat $($in $kJ)$ is required to convert $111g$ of solid water at $-31\mathrm{.}0C$ to

water vapor at $125C.$

Hint: You will need five equations that you add together because the water is a

liquid.

Tip $1$: Three equations use $m$ and the other two use $n.n$ is moles. $m$ is mass in

grams. You should put the final units for both in terms of grams.

Tip $2$: One equation will come out in J$.$ One will come out in $kJ.$ You have to put

them both in $kJ$ before you can add them.
