The size of an atom is roughly 10^-10 metres
10^-10 • 100,000,000 = 0.01 metres
Since 1 metre = 100 centimetre
0.01 x 100 = 1 centimetre
There’s your answer
Answer: gaseous molecules are far apart
Explanation:
One of the states in which matter exists is gas. Gases are made of up molecules that are far apart, travelling randomly and rapidly within the containing vessel.
Hence, they are easy to compress whereby they occupy limited space as the gaseous molecules are closely packed in vessels like cylinders and transported to places where they may be needed.
Answer:
7.5 L
Explanation:
At constant temperature and number of moles, Using Boyle's law
Given ,
V₁ = 3.00 L
V₂ = ?
P₁ = 36.74 psi = 2.5 atm (Conversion factor, 1 psi = 0.068046 atm)
P₂ = 1 atm (Atmospheric pressure as it comes to surface)
Using above equation as:

Answer:
0.40 L
Explanation:
Calculation of the moles of
as:-
Mass = 51.24 g
Molar mass of
= 171.34 g/mol
The formula for the calculation of moles is shown below:
Thus,

Volume = 1.20 L
The expression for the molarity is:


Thus,
Considering
Given that:
So,
<u>The volume of 0.24925M stock solution added = 0.40 L
</u>
