the mole concept
mole and mass
atoms
mass number(元素周期表字母下面的数字)
mlecules
需计算molecules总共的mass number
mole 和质量数相同,多少质量多少mole
from "mole"------✖️-----mass number
from "mole"------➗-----mass number
不固定换算比率
/
atoms molecules不同
mole and volume
固定换算比率/atoms molecules相同
for gases only
atoms
molecules
1 mole =24 dm^3 molecules
mole and particles
atoms(contain only 1 element)
from "mole"------✖️-----6✖️10^23
molecules(compound/more than one element)
from "particles"------➗-----6✖️10^23
"mole"大,atoms和molecules换算方法相同
固定换算比率
/
atoms molecules相同
question involve mole concept
1.列出对应的条件(已知条件,要求的条件,标在equation下)
2.将已知的条件(mass/volume/con[centration)通过不同形式的换算(24dm^3/mass number/6✖️10^23)转换成mole 的形式
3.列出已知和要求条件的比例,将比例从mole的形式转换成题目要求的单位量
