a) Answer:
Number of molecules in 1 mole
Explanation:
a) Whether we take any of the substance among all three of the given substances they will have the same number of molecules in 1 mole of the substance is considered and the value for this will be [tex]6.023 x 10^23[/tex]
b) Answer:
In the given question mass of the substance which is greatest is asked for one mole and we also know that mass of one mole is given by molar mass.
Explanation:
b) It is known that [tex]31.98g/mol[/tex] is the molar mass for oxygen which is greater than that of hydrogen while fluorine has a molar mass of [tex]38.0 g/mol[/tex] which on comparison shows that, it is the highest amongst all three.
