The final temperature of the mixture will be <u>30⁰C</u>
Since it is given that 50 gms of water at 20 ⁰ C and 50 gms of water at 40⁰ C are mixed. Since the masses of the liquid at different temperatures are the same, the answer is very easy and simple: average of 20⁰C and 40⁰C. that is 30⁰C.
<em>the final temperature of the mixture = </em>
<em> = [ m1 * T1 + m2 * T2 ] / (m1 + m2)</em>
<em> = [ 50 gms * 20⁰ C + 50 gms * 40⁰C ] / (50+50)</em>
<em> </em><em> = 3,000 / 100 = </em><u><em>30⁰C</em></u>
In chemistry, we define the temperature of a substance as the average kinetic power of all of the atoms or molecules of that substance. No longer do all of the debris of a substance have identical kinetic strength. At any given time, the kinetic energy of the debris may be represented by means of a distribution.
Temperature performs a vital function in-hospital treatment (both humans and animals), food, beverages, and agriculture. Our average fitness is regularly reliant upon the temperature in lots of methods as nicely.
The SI unit of temperature as consistent with the global system of devices is Kelvin.

Answer:
The molar mass of is 342.145 g/mol
Explanation:
The molar mass is stated as the “mass per unit amount of substance”of a given chemical compound
is Aluminium sulphate. They easily dissolve in water. It is primarily used as a 'coagulating agent' in the drinking water purification and also in waste and sewage water treatment plants,
We know,
Atomic weight of Aluminium = 26.981
Atomic weight of Sulphur= 32.065
Atomic weight of Oxygen = 15.9994
Now molar mass of (Aluminium sulphate) is
=>2(26.981)+3(32.065+4(15.999))
=>53.962 +3(32.065+63.996)
=>53.962+3(96.061)
=>53.962+288.183
=>342.145
Density can be calculated using the following rule:
density=mass/volume
therefore,
volume=mass/density
we have mass=0.451g and density=0.824g/ml
substituting in the above equation, we can calculate the volume as follows:
volume = 0.451/0.824 = 0.547 ml
