The study of chemicals is called chemistry. There are two types of solution in the chemistry and these are acid and base.
The correct answer to the question is as follows:-
What are moles?
- The mole is the base unit of the amount of substance in the International System of Units.
- It is defined as exactly 6.02214076×10²³ elementary entities, which may be atoms, molecules, ions, or electrons.
The reaction is as follows:-
\(2H_2O ---> 2H_2 + O_2\)
The moles are as follows:-
- (\(\frac{(50.00g O2)}{(32.00g/mol O2)}\)= 1.563mol O2
- \(\frac{(1.563mol O2)}{(\frac{2mol H2O}{1mol O2)}}\)= 3.125mol H2O
- \(\frac{(3.125mol H2O)}{(\frac{18.01g}{1mol H2O)}}\) = 56.28g H2O needed to make 50.00g O2
Hence, the correct answer is 56.28.
