Answer 1

We can first find the weight of the other elements which are less heavier than oxygen:
38.6-20.4
=18.2kg

To find her weight,we can add up the weight of all elements:
18.2+38.6+6.1
=56.8+6.1
=63.1 kg

Therefore Anne’s weight is 63.1 kg

Hope it helps!

Answer 2

Answer with explanation:

Weight of Oxygen in Anne's body =38.6 Kg

Weight of Hydrogen in Anne's body =6.1 Kg

Weight of Other Elements in Anne's Body =20.4 Kg less than than the weight of oxygen.

     =38.6 Kg - 20.4 Kg

     = 18.2 Kg

So,Weight of  gases in Anne's body =38.6 Kg +6.1 Kg +18.2 Kg

                                                              =62.9Kg
