You could save yourself a lot of typing woes if you omitted all of those extraneous symbols. I know you're trying to help us understand the problem because all of those symbols aren't available on keyboards but we've been a this long enough to know what the keyboards mean.
q = mass x specific heat x delta T.
q = 685 J. Substitute for the other variables and solve for specific heat.
