Answer :
2KClO₃ ⇒ 2KCl + 3O₂
2mol : 3mol
245,1g : 95,94g
x : 7,8g
x = 7,8g*245,1g / 95,94g = 19,93g
1mol of KClO₃ --------- is --------- 122,55g
x mol --------- is --------- 19,93g
x = 19,93g*1mol / 122,55g = 0,158mol
2mol : 3mol
245,1g : 95,94g
x : 7,8g
x = 7,8g*245,1g / 95,94g = 19,93g
1mol of KClO₃ --------- is --------- 122,55g
x mol --------- is --------- 19,93g
x = 19,93g*1mol / 122,55g = 0,158mol
