When 67 g of water is heated from its melting point to its boiling point, it takes 28006 J of heat.
<h2>Relationship between heat production and temperature change</h2>
- A way to numerically relate the quantity of thermal energy acquired (or lost) by a sample of any substance to that sample's mass and the temperature change that results from that is provided by specific heat capacity.
The following formula is frequently used to describe the connection between these four values.
q = msΔT
where, q = the amount of heat emitted or absorbed by the thing
m = the object's mass = 67 gm
s = a specific heat capacity of the substance = 4.18 J/gC
ΔT = the resultant change in the object's temperature = 373.15 -273.15K= 100 k
q = 67 * 4.18 * 100 J
⇒q = 28006 J
Therefore it is concluded that 67 g of water takes 28006 J of heat from its melting point to reach its boiling point.

Dissociation
NH₄NO₃(aq) = NH₄⁺(aq) + NO₃⁻(aq)
the hydrolysis of the cation
NH₄⁺(aq) + H₂O(l) = NH₃(aq) + H₃O⁺(aq)

We know that there are 760 mmHg per 1 atm. So in order to make this conversion, we need to set up the multiplication to cancel out the atm and leave mmHg on top. Let's set that up now and solve:
So by using this conversion factor, we are able to determine that
0.600 atm = 456 mmHg.
