At 298K and 1bar pressure, the density of water is 1.00 g/cm^3 , Cpm = and 75.3 J/Kmol. The change in volume with temperature is given by delta V = ViB(deltaT), where B, the coefficient of thermal expansion, is 2.07 * 10^-4 K^-1.

If the temperature of 350g of water is increased by 27.5K , calculate w.

How do I start this question?

    Do you have a typo? Cpm = and 75.3 j/kmol makes no sense.
    Calculate w but w isn't anywhere in the problem.

  • Chemistry - ,

    It should be and Cpm = and 75.3 J/Kmol. I know w isn't anywhere in the problem which is why I don't know where to start.

  • Chemistry - ,

    and Cpm and 75.3 still doesn't make sense. So what does w stand for. It might help if we knew what we for looking for.

  • Chemistry - ,

    w = work, it's a physical chem question, here c does not mean concentration, it is the heat capacity of pressure/mole
