The molecular formula : C₄H₈O₂
<h3>Further explanation</h3>
Maybe a compound is 54.5% carbon, 9.1% hydrogen and 36.4% oxygen,so :
mol C :
mol H :
mol O :
Divide by 2.28(the smallest ratio) :
C H : O =
The empirical formula : C₂H₄O
(The empirical formula)n=molecular formula
(2.12+4.1+16)n=88
(44)n=88⇒n=2
yes.

Answer:
Space junk is travelling so fast that a collision with an astronaut or a spacecraft could be disastrous.
Explanation:
Space junk orbits the Earth at speeds of about 28 000 km/h.
That's so fast that even an orbiting fleck of paint has enough kinetic energy to cause impact craters on the surface of a spacecraft. They are even more dangerous to an astronaut on a space walk.
Much of the space debris is larger and more dangerous than a fleck of paint.
One rough estimate of the amount of space debris is
<em> </em><u>Size</u><em> </em> <u>Number of objects</u>
< 1 cm 200 000 000
1 cm to 10 cm 700 000
> 10 cm 30 000
Satellites, etc. 18 000
The chances of collision are small, but any collision can be disastrous.
