How do i find the q of a rxn if the density of water is 1.0g/ml and the cs is 4.18 j/g*c?
i have 50ml of 1m hcl and 50ml of 1m naoh, and the change in temperature was 6.4c.
i got -2675.2j, but i have no idea if that seems reasonable. the equation is: q of rxn = (-m of soln)(cs)(change in temp of soln).
