Hey guys, this is my first post here. I really have no clue how to go about solving this problem, could someone guide me through it?

Given 360.5 g of hot tea at 80.0°C, what mass of ice at 0°C must be added to obtain iced tea at 10.5°C?
The specific heat of the tea is 4.18 J/(g·°C), and ΔH_fusion for ice is +6.01 jK/mol.

Ok, what formulae do you know.

Also, start by converting that lone molar quantity into per-gm.

I know this formula. (I'm not really sure what you would call it, it's related to Gibbs free energy obviously, but I really have little to no idea where the formula comes from.)

ΔG = ΔH - TΔS

Additionally, the formula to calculate a change in heat
ΔQ = mcΔT

Otherwise,

ΔH = ΔE - PΔV.

Can't think of any other relevant formulae off the top of my head.

Additionally, the formula to calculate a change in heat
ΔQ = mcΔT

Good. That's one. But only for specific heat. What about latent heat.

No idea. Let me try to find one, lol. (PS, i'm teaching myself without a textbook ahead of the curriculum schedule, so my knowledge is just pretty much parsed together from online free educational resources. It's choppy at best atm.)

Are you referring to Q = mL?

Yes. That's it. Only equations you need.

ΔQ = mcΔT

Also, to be pedantic, one doesn't use a Δ with Q. Q isn't a state function.

i.e. You can talk about "heat"  but "change in heat" is not meaningful.

Okay, thanks so much for your help. I'll see what I can do with this and come back sometime later with an answer or question if I have one.

I remember that equation from high school chemistry, and I have to say, my teachers regularly used delta with Q. I'll trust you on it, but is it some sort of inefficient but accepted norm like measurement units in the US or Pi over Tau or something like that? (Or were my teachers just the oddballs.)

....or I could be wrong.

Let's see if someone else chimes in.
