Bonjour, je n'arrive pas à trouver comment calculer la masse molaire du carbone 14, je bloqué.
Est-ce que quelqu'un peut m'expliquer ?
J'ai essayé avec la formule
M = m × Na.
M = 12,0 × 6.022 × 10²³
M = 7.2264 × 10²⁴
Je ne suis pas sûre si c'est bon. ça à l'air faux
Mais je n'arrive pas à comprendre comment ça fonctionne.. merci beaucoup
