Explanation:

so for this one you know 92.24 is the mass of C so to work out the mass of hydrogen u so 100-92.24=7.76

C : H

92.24/12 : 7.76 /1

7.68 : 7.76

so 7.76÷7.68=1.01

so CH

12+1=13

78.12÷13=6.009

so CH×6= C6H6

hope this helps:)

AURORKA [14]

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 $6.023 x 10^23$

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 $31.98g/mol$ is the molar mass for oxygen which is greater than that of hydrogen while fluorine has a molar mass of $38.0 g/mol$ which on comparison shows that, it is the highest amongst all three.
