Explanation:
According to the heat relationship,
Heat given by steam = heat taken by water
Hence, 
= 
where, 
= specific heat
Value of 
at 250^{o}C and 12.5 atm is 2.326 
.
And, at 200^{o}C and 12.5 atm is 2.743 .
Therefore, average = 
= 2.5345 kJ/Kg^{o}C
As the given data is as follows.
= 400 kg/hr, 
= 
= 
, 
= 500 kg/hr
= 4.186 
Hence, putting the given values into the above formula as follows.
=
= 
As we know that, 
Thus, we can conclude that the new temperature of water is 
.
On average, seawater in the world's oceans has a salinity of ~3.5%. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.
<h3>What is salinity ?</h3>
The saltiness or quantity of dissolved salt in a body of water is known as salinity (see also soil salinity). The standard units of measurement are grams of salt per liter (g/L) or grams per kilogram (g/kg; the latter is dimensionless and equal to ).
Salinity is a thermodynamic state variable that, along with temperature and pressure, controls physical properties like the density and heat capacity of the water. Salinity plays a significant role in determining many aspects of the chemistry of natural waters and of biological processes within them.
An isohaline, or isohale sometimes, is a contour line with a constant salinity.
The concept of salinity in rivers, lakes, and the ocean is straightforward, but it is difficult to define and measure properly on a scientific level.

Explanation:
Hello!
In this case, we need to keep in mind that performing these types of operations require that the final result was shown with the same significant figures as the initial number with the fewest ones; it means, we show the final result with 3 significant figures, because 3.698 has four and 1.85 has three significant figures; therefore, we obtain:
Best regards!
Ammonia is NH3, meaning there are three bonds. All three bonds are between nitrogen and hydrogen, one each per hydrogen atom. If dissolved in water, they can also be called ammonium hydroxide. (NH4OH)
