The empirical formula is XeO₃.
<u>Explanation:</u>
Assume 100 g of the compound is present. This changes the percents to grams:
Given mass in g:
Xenon = 73.23 g
Oxygen = 26.77 g
We have to convert it to moles.
Xe = 73.23/
131.293 = 0.56 moles
O = 26.77/ 16 = 1.67 moles
Divide by the lowest value, seeking the smallest whole-number ratio:
Xe = 0.56/ 0.56 = 1
O = 1.67/ 0.56 = 2.9 ≈3
So the empirical formula is XeO₃.
I think its 14 - 5 and you get 9
answer:
A
explanation:
it have to be balanced to form water
and water is H2O
If this is meters, then it’d be 1310.
1km = 1000m
.31 x 1000 = 310
So, 1000 + 310 = 1310m
