how do i solve What mass of water can be heated from 25 degrees Celsius to 50 degrees Celsius by the addition of 2825 J? Express your answer as a number only with two sig figs.
Homework Answers
We know , 
Q is the heat (here 2825 Joule )
m is the mass of substance
S is the specific heat ( for water , it is 4.186 Joule per gram per 0C)
T is the temperature change in Celcius or Kelvin scale ( Here T=(50-25)0C=250C)
Thus , the mass of water is 26 grams .
Maintaining only number and 2 significant figure , we can say , answer is 26 .

155 grams of ice at -10.0 degrees celsius is added to 1.17 kg of water at 70.0 degrees celsius and mixed together in thermal isolation until they come to equilibrium. The specific heat of ice is 2010 J/kgC. The specific heat of water is 4186 J/kgC. The latent heat of fusion for water is 3.34x10^5 J/kg. The latent of vaporization for water is 2.26x10^6 J/kg. What is the final equilibrium. The answer is 51.9 celsius. I just need the steps...

A solution of ethylene glycol in water at 20 degrees celsius has a mass percent of 9.78% of ethylene glycol with a density of 1.0108 g/mL. The freezing point depression constant for water (solvent for all solutions) is Kf=-1.86 percent celsius kg/mol and the boiling point elevation constant is Kb=0.512 degrees celsius kg/mol. The density of neat water at 20.0 degrees celsius is 0.9982 g/mL. Answer the following: 1. What is the molarity of the solution? 2. What is the...
