5000 units of antigens are present in 0.5 mL of the mumps virus vaccine.
Volume of the vaccine after dilution with water = 2 mL
0.5 mL has 5000 units antigen. So when 0.5 mL was diluted to 2 mL, the final vaccine after dilution would contain 5000 units of antigen.
Units of antigen present in 1 mL vaccine sample
=
Therefore, 2500 units of the antigen will be present in each milliliter, if 0.5 mL of the vaccine is diluted to 2 mL with water for injection.
When changing states, only the intermolecular forces are considered, which, in water's case are hydrogen bonds. In order to go from solid to liquid to gas, the hydrogen bonds between the water molecules must be weakened to a certain degree that allows the molecules to spread further apart in liquids, and must be broken altogether to separate the molecules in order to turn it into gas.
Therefore, the answer is d.
The reason it is not the covalent bonds within molecules (despite the fact that it will turn water into a gas, it’s not water vapour, but hydrogen and oxygen gas) is that when bonds within a molecule are broken, this is called decomposition and it is a CHEMICAL change. Changing states is only a PHYSICAL change.
It is not ionic because water has covalent bonds.
Hydrogen bonds can only occur BETWEEN molecules (intermolecular forces).
Covalent bonds can only occur WITHIN molecules (intramolecular).
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
The law of conservation of energy states that energy can neither be created nor destroyed.
It can only be converted from one form of energy to another.

Answer:
<h2>5080 mL</h2>
Explanation:
The volume of the gas at standard pressure can be found by using the formula for Boyle's law which is
Since we are finding the new volume
From the question we have
We have the final answer as
<h3>5080 mL</h3>
Hope this helps you
