Homework Statement
When 10.00 mL of a solution of strong acid is mixed with 100.00 mL of a solution of weak base in a coffee-cup calorimeter, the temperature falls from 25.7oC to 20.7oC. Determine q for the acid-base reaction, assuming that the liquida have densities of 1.00 g/mL and the same heat capacities as pure water.
Homework Equations
So I see that you're supposed to use the Q = (Change in T)(N)Molar Heat Capacity of H2O) but they've given the density of water so we're supposed to convert that into moles. I'm obviously doing something wrong, but does anyone know how to convert the density into moles?
Density = Mass (g) / Volume (L)
moles = Mass(g) / Molar Mass (g/m)
