如果題目俾左你
Element W的Mass no. = 24
Element Z的Mass no.= 35
佢地combine埋做左一個compound = WZ
咁relative formula mass = 24+35 = 59
如果題目要求你計既係" formula mass",而不是"relative formula mass",咁係咪跟返periodic table上面個數字?

✔ 最佳答案
"Formula mass" is the short form of "relative formula mass". Actually, the two terms are identical.No matter whether "formula mass" or "relative formula mass" is calculated, all of the method, steps and answer are the same.

唔係應該
formula mass = mass number + mass number +...
relative formula mass = relative atomic mass + relative atomic mass+...(periodic table個數字)
咩?
formula mass = mass number + mass number +...
relative formula mass = relative atomic mass + relative atomic mass+...(periodic table個數字)
咩?
