Q=MS∆T Question

  1. Apr 8, 2010 #1
    1. The problem statement, all variables and given/known data
    Unknown gas:
    Solving for Q
    2.5 moles
    Molar heat capacity 2.00J/mol°C
    P constant .995

    My question is I'm used to seeing this eqn. with specific heat and grams. Since given molar heat capacity and moles does it still work?
    Constant P allows me to ignore it in this type of eqn?

    2. Relevant equations

    3. The attempt at a solution

    Q=(2.00J/mol°C)(2.50 mol)(20.5 °C) = 102.5 J

    Your units match up, and it looks good to me.
