How many grams of water could be raised from 25 C (room temp) to 100 C (boiling point of H2O) by the amt of?
Ivory asked:
energy released in the formation of 1 mol H2 from hydrogen atoms? The bond energy of H2 is 435 kJ/mol
energy released in the formation of 1 mol H2 from hydrogen atoms? The bond energy of H2 is 435 kJ/mol
The answer is 1400g
But i dont know how they got that. What formula or conversion factor are we sopposed to use. Im so confused. Please help

= Entalpía (Cp x T x m) / (1000 x n) Cuando entalpía es de 435, Cp es 4,18 (densidad de energía de agua), T es el cambio de temperatura (100 – 25), m es la masa de agua (el lo que quiere), n es el mol de gas de hidrógeno (1) . Por lo tanto, volver a organizarse es para: m = (entalpía x 1000 x n) / (Cp x T) La respuesta es 1387g = 1400g (2 s.f.)
