the Earth is eccentric,this means that it has changed repeatedly over time
And if it took the earth more time to orbit round the sun than it does now the years would have more than Han 365 days a year

I bolded the 4 hydrogens that can be subsituted by sodium.
Three of those hydrogens belong to carboxyl group (- CO2H) and one to a hydroxyl group (- OH).
You need to take into account that 4 H will form 2 H2 molecules.
So, the answer is that 2 moles of molecules will be formed from 1 mole of citric acid molecules.
Answer: 45 moles H2O
Explanation: To solve for the moles of H2O in the reaction we will use the mole ratio of O2 and H2O based from the chemical equation which is 1 : 2
22.5 moles O2 x 2 moles H2O / 1 mole O2
= 45 moles H2O
