Question

At 1 atm, how much energy is required to heat 77.0 g of H2O(s) at –10.0 °C to H2O(g) at 157.0 °C? Helpful constants can be found here.

Answer 1

Look up the constants and then use:

q = mCdeltaT

q= m delta H_fusion

q = m delta H_vaporization

Add them all up. You should have FIVE separate calculations of q
