Question

Calculate the heat change in joules for condensation of 7.10 g of steam at 100 C.

Please express answer as a positive value using three significant figures and include the appropriate units.

Answer 1

$\Delta H_{Cond}=2257J/g$

Mass of water$=7.10g$

$\Delta H=?$ $kJ$

$(2257 J/g) \times (7.10 g) = 16025 J$

$=$ $16025J\over 1000$ $=16.025kJ$
