Thank you for the opportunity to help you with your question!

Weight of oxygen in Anne's body = 38.6 kg

Weight of hydrogen in Anne's body = 6.1 kg

The weight of other elements is 20.4 kg less than the weight of oxygen.

So, weight of other elements = 38.6 - 20.4 = 18.2 kg


Anne's weight = Weight of oxygen + Weight of hydrogen + Weight other elements

Anne's weight = 38.6 + 6.1 + 18.2

Anne's weight = 62.9 kg
