Explanation:
Hello!
In this case, since the reaction between hydrogen and oxygen to produce water is:
When equal masses of each reactant go in contact to carry out the reaction, we can identify the maximum mass of yielded water as the fewest mass yielded by each reactant, just as shown below:
Thus, since hydrogen yields more water than real, we limit the maximum mass of water to those 55.2 g yielded by oxygen as hydrogen would be in excess.
Best regards!

The answer is 24 g.
no.of moles = given mass / molecular mass
By re-arranging formula, we get,
no.of moles * molecular mass = given mass
(putting up the values)
2*12 = given mass
24 g = given mass
hope it helps plz mark me bramliest..
