Therefore, you don't need mass to calculate q. Formula q = mc t, where q is heat in joules, c is specific heat capacity in j/g c, m is the mass in grams, and delta t is the change in temperature in c. Liquid q 1 = m x c x ∆t 100 0 c liquid → gas q 2 = m ∆h vap 100 0 c to 125 0 c gas q 3 = m x c x ∆t total 524.25 kj Q = mc δ t.
