Answer:
9 grams
Explanation:
Hope it can help you.....
Co2 is made of carbon ( atomic mass: 12) and oxygen (atomic mass : 16)
First : mass of 1 C atom + mass of 2 O atom = 12+(16*2)=44 amu so 1 mole CO2 =44 grams then 2.5 mole CO2 =44*2.5 =110 grams
So the answer is 110 grams
In the Lewis symbol for a fluorine atom, there are <u>4</u> paired and <u>1</u> unpaired electrons.
However, paired electrons simply means are 2 electrons occupying the same orbital in an atom or molecule of a substance
On the other end, unpaired electron is a single electron that occupies an orbital of an atom.
<h3>What is an atom?</h3>
An atom is the smallest part of an element which can take part in a chemical reaction.
Some atoms of elements are:
- Monoatomic
- Diatomic
- Triatomic
- Polyatomic
In conclusion, in the Lewis symbol for a fluorine atom, there are 4 paired and 1 unpaired electrons.

Answer:
2,500,000 litres or 2.5 megalitres of water.
Olympic size pools measure: 50 metres long, 25 metres wide, and a minimum of 2
metres deep.
(25m x 50m x 2m = 2,500m3; 1L = 0.001m3 so 2,500 x 1000 = 2,500,000L)
660,430 gallons of water.
50 meters = 164.041995 feet (a)
25 meters = 82.0209975 feet (b)
2 meters = 6.5616798 feet (c)
Volume = (a) * (b) * (c) = 88,286.66721 cubic feet Explanation:
