You are given 100 g of coffee (same specific heat as water) at 80.0° C (too hot to drink). In order to cool the coffee to 50.0° C (neglect heat content of the cup and heat exchanges with the surroundings) calculate: a. How much tap water at 20.0° C must be added? b. How much ice (at 0.0° C) must be added? c. How much ice (at -10.0° C) must be added? 2. How much energy is required to heat 7.5 kg of ice at -30°C to steam at 200°C?

a. How much tap water at 20.0° C must be added?

b. How much ice (at 0.0° C) must be added?

c. How much ice (at -10.0° C) must be added?

I've found how much energy it takes to go from 80 C to 50C but I'm unsure how to Get grams
