Ответ:

тебе тут надо вычеслять , но я объясню как

Объяснение:

Молярная масса находится так: ты Атомную массу (которая есть на 1 или 2 форзаце ) умножаешь на количество атомов (если они есть) , если состоит из двух веществ то складываешь

например (Н20) У Н Атомная масса=1 , но атомов у неё 2 , а у О атомная масса равна 16 , значит 1×2+16=18

Масса молекулы находится по формуле

n=N/Nавагадро , но тебе сначало нужно найти химическое количество (n ) по формуле n =m/M(молярная масса)

ЗНАЮ НИЧЕГО НЕ ПОНЯТНОО

Young people are active participants in theirown history. Past generations of radicalstudents have played a part in protests andrevolutions against the existing order ofsociety. A youth movement in this sense hasan ideological or political character.

At the same time ordinary young peopleusually belong to a youth movement throughmembership of an adult-led, voluntary youthorganization, such as the Scouts or Guides.There are also fashion-led “youth cultures”,identified by types of dress, music andlanguage. The term “youth movement” is sowide that it can refer to Punk Rockers as wellas the Young Conservatives.
The world’s first voluntary youth organization was the Church-based Boys’ Brigade,founded in Glasgow , Scotland, in 1883 by William Alexander Smith (1854-1914) anddedicated to religious education and developing the habits of Obedience, Reverence,Discipline, Self-Respect, and all that tends towards a true Christian manliness.

In the 1900s, in Germany appeared a movement of middle-class students who took upopen-air tramping. Richard Schirmann, a German schoolteacher, opened the first youthhostel in 1909. Youth hostels providing cheap accommodation for young people arenow found in most areas of the world.

In England, Major-General Robert Baden-Powell (1857-1941) founded a uniformedwoodcraft movement – the Boy Scouts – in 1908. Like the Boys’ Brigade, the Scoutmovement has spread around the world. A sister organization to the Scouts, the GirlGuide Association, founded in 1910, also has a large membership worldwide. Theseorganizations train boys and girls in various useful skills, such as lighting a fire,cooking, fishing, and for developing their character. Scouts traditionally carry apenknife and their motto is “Be prepared”.
Young people have contributed to mass politicalmovements of both left and right. In the 1930s therefunctioned youth Fascist organizations in Mussolini’sItaly and Hitler’s Germany. After 1933 membership ofthe Nazi Hitler Youth became compulsory. In Britainsome young people joined the Blackshirts. TheAustrian Red Falcons were an active 1930s socialistmovement.Soviet Russia had Young Communist groups:Octobrist, Pioneer and Komsomol whose aim waspolitical education of young people.

Since World War II the media have spoken a lotabout the activities of various notorious youthcults, thus spreading information about them.The Teddy Boys of the 1950s, with their longjackets, velvet collars, drainpipe trousers andcrepe-soled shoes were the firs of the rebelliousworking-class youth cults. In the early 1960scame new groups such as the Mods, dressed inItalian-style clothes, and their leather-clad rivals,the Rockers, associated with motorcycles androck-and-roll music.The Hippies of the late 1960s were more middle-class. They experimented with drugs, lived incommunities, grew their hair long, and wereattracted to radical politics.Skinheads, combining elements of both Modsand Rockers and associated with the racism ofthe far right, arrived on the scene in the late1960s. Punk Rockers achieved notoriety throughthe attention of the media in the late 1970s, withtheir unique “Mohican” hairstyles, vivid make-up,cast-off clothes and aggressive music. Several ofthese youth cultures were recycled in the 1980s.
