Answer:
Units of a = 
Units of b = 
Explanation:
The Van der Waal's equation is:-

Where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value
a and b are van der Waal's constant
If pressure is taken in atm and volume in L. So,
represents the pressure correction term. Then,
Units of a = 
represents the volume correction term. Then,
Units of b = 
Rate of reaction can be understood as the rate of change of the materials, such as the rate of depletion of the reactants or the rate of production of products. Therefore, if a graph of concentration and time is plotted, the rate of reaction is simply the slope of the graph.
Scientific methods are used to study living things or investigate questions and solve problems.
It is a covalent bond. Whenever a compound uses such suffixes like mono, di, tri, tetra, and so on, it is a covalent compound- thus having covalent bonds.
<u>Answer:</u> The molarity of solution is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

We are given:
Mass of solute (CAMP) = 0.0000000342 g
Molar mass of CAMP = 329.21 g/mol
Volume of solution = 1 L
Putting values in above equation, we get:

Hence, the molarity of solution is
