<u>Answer:</u> The amount of CO that is occupied in the room is 
<u>Explanation:</u>
We are given:
Concentration of CO = 
by volume
This means that 
of CO is present in 1 L of blood
To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 10.99 m
b = breadth of cuboid = 18.97 m
h = height of cuboid = 11.89 m
Converting this into liters, by using conversion factor:
So, 
Applying unitary method:
In 1 L of blood, the amount of CO present is 
So, in 
of blood, the amount of CO present will be = 
Hence, the amount of CO that is occupied in the room is
Answer:
Using cobalt glass could be helpful to identify elements that weakly emit blue and/or violet.
Explanation:
1) For example, sodium oxide (Na₂O).
One one molecule of sodium oxide has one sodium atome (Na) and two oxygen atoms (O).
The subscript after element shows the number of elements in a molecule.
2) Yes, it possible for two different compounds to be made from the exact same two elements.
This are isomers, same molecular formula, but different arrangements of atoms.
For example, n-butane (C₄H₁₀) and 2-methylpropane (C₄H₁₀).
3) There are large number of compounds in this world, around 40 millions.
100+7.8=107.8 degrees. Which is now your new boiling point.
