Answer:

The correct answer is 2.33g of
H_(2)O, A

Step-by-step explanation:

We can use basic stoich to get this question.

To start, lets convert our grams to moles in order to use our equation. 5.38g of
O_(2) = ((5.38)/(2*15.999)) moles = 0.168136 moles.

We then can use our molar ratio of 13:10. Simply divide by our molar ratio in order to go from moles of
O_(2) to moles of
H_(2)O. This gets us 0.129335 moles of
H_(2)O.

Now lets convert to grams of
H_(2)O by multiplying by the molar mass of
H_(2)O.
.129335*(1.008*2+15.999) = 2.32997g of
H_(2)O
