Education is an important tool which is very useful in everybody’s life. Education is what differentiates us from other living beings on earth. It makes man the smartest creature on earth. It empowers humans and gets them ready to face challenges of life efficiently. With that being said, education still remains a luxury and not a necessity in our country. Educational awareness needs to be spread through the country to make education accessible. But, this remains incomplete without first analyzing the importance of education. Only when the people realize what significance it holds, can they consider it a necessity for a good life. In this essay on Education, we will see the importance of education and how it is a doorway to success.
Объяснение:
значит объем кислорода = 22,4/5 = 4,48л
кол-во вещества ксилорода = 4,48/22,4 =0,2моль
азота в воздухе примерно 78% по объеаму, значит объем его =17,47л
кол-во азота -17,47/22,4=0,78моль
1 моль любого вещества содержит 6,02*10^23 молекул
кислорода = 0,2*6,02*10^23 = 1,2*10^23молекул
азота = 0,78*6,02*10^23 = 4,7*10^23молекул
