Answer:
Q = 143,921 J = 143.9 kJ.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the absorbed heat by considering this is a process involving sensible heat associated to the vaporization of water, which is isothermic and isobaric; and thus, the heat of vaporization of water, with a value of about 2259.36 J/g, is used as shown below:

Thus, we plug in the mass and the aforementioned heat of vaporization of water to obtain the following:

Answer:

Explanation:
Hello.
In this case, since the neutralization of the acid requires equal number of moles of both acid and base:

Whereas we can express it in terms of concentrations and volumes:

Thus, we can compute the volume of sodium hydroxide (base) as follows:
