Moles of methanol present in 2.5 L of 0.25 M solution
Moles of CH3OH = 2.5 * 0.25 = 0.625
Mass of CH3OH = 0.625 * 32 = 20 g
(∵ Molecular mass of CH3OH = 12 + 1 * 3 + 16 + 1 = 32)
0.793 * g of CH3OH is present in 1000 mL
20 g of CH3OH is present in
= mL

➧ Types of Biodiversity are:-
[1] Genetic Diversity:-
❱ The total number of genetic characteristics in the genetic makeup of a species.
[2] Species Diversity:-
❱ The number of different species that are represented in a given community.
[3] Ecosystem Diversity:-
❱ The the variety of different ecosystems within an area.

Elsa was Einstein's cousin who used to live in Berlin where her father had his business. She believed that one must learn just enough to pass exams. She observes that one does not have to know anything or understand what is being taught but just be able to repeat it in the exams. To learn to repeat things like a parrot and reproduce it in the exam hall. Elsa does not read anything other than what is prescribed in her school,she has no thirst for knowledge and will not study anything that is not required as per her coursework. She advised Einstein to do the same and just get his diploma because kids dumber than him would get it easily without putting in any effort.

The comparison made between rain and music is definitely a suitable metaphor. The poet says that water rises, and falls onto the earth, returning beauty to nature in the form of flowers and other plants. Similarly, music resonates from the musician, evoking thoughts, ideas and emotions from the soul of the listener. Feelings which lie dormant in the mind of the listener come out only when listening to music, just like seeds that lie buried under the earth, that sprout into plants after rainfall.

The water from above inevitably clear everything thing that comes in it's the way and makes it dust-free as the object was just as before, which eventually helps the earth to be clean and help to maintain it's beauty.

The term “isotope” mainly refers to the variation in the atomic mass or weight of an element.
It is also defined as variants of a particular element where these variants will have the same number of protons but differ in the number of neutrons in the atom.
When we look at carbon it also has three isotopes namely Carbon-12, Carbon-13, and Carbon-14. The numbers 12, 13, and 14 are the isotopes’ atomic masses. Here, Carbon-12 is a stable isotope whereas carbon-14 is mostly a radioactive isotope.

Step -by -step explanation:
tan20° tan40° tan80°
= 2sin20°sin40°sin80°/2cos20°cos40°cos80°
= {cos(20°-40°)-cos(20°+40°)}sin80°/{cos(20°+40°)+cos(20°-40°)}cos80°
= (cos20°-cos60°)sin80°/(cos60°+cos20°)cos80°
= {2cos20°sin80°-2(1/2)sin80°}/{2(1/2)cos80°+2cos20°cos80°} [∵,cos60°=1/2]
= {sin(20°+80°)-sin(20°-80°)-sin80°}/{cos80°+cos(20°+80°)+cos(20°-80°)}
= (sin100°+sin60°-sin80°)/(cos80°+cos100°+cos60°)
= {2cos(100°+80°)/2sin(100°-80°)/2 +√3/2}/{2cos(100°+80°)/2cos(100°-80°)/2+1/2} [∵, sin60°=√3/2 and cos60°=1/2]
= (2cos90°sin10°+√3/2)/(2cos90°cos10°+1/2)
= (√3/2)/(1/2) [∵, cos90°=0]
= √3
= tan60°
Now, tan30°tan60° = *= 1
