1- Masse molaire du glucose:
C6H12O6
C= 6x12=72
H=12x1=12
O=6x16=96
Donc 72+12+96=180 g
Masse molaire du Saccharose:
C12H22O11
C=12x12=144
H=22x1=22
O=11x16=176
Donc 144+22+176= 342 g
Voilà :)

Bonjour, ce texte est-il bien traduit ? y a-t-il des erreurs ? London : Big Ben Big Ben is the national symbol of the British unit and of the Westminster Palace. Big Ben is the name of the bell, originally called "The Great Bell ." It is named to Benjamin Hall, the engineer. In 1856 , the first bell is installed but a fire devastated a part of the building of parliament and the bell is cracked. A renovation is then provided . In 1859, a new bell was installed. She has a very distinctive tone due to a crack, two months after installation. The air Carrillon is also called " Westminster Quarters " . The building faces the River Thames, between Westminster Bridge and Westminster Abbey . When parliament is inside a British flag floating above the clock and a light turns on . Big ben illuminated at night. It is forbidden to tourists , only residents have the right to raise its 335 steps. There is also a small clock tower, close to Victoria Station, called "Little Ben"Merci d'avance :)
