Answer:7M
Explanation:
There are different methods to express the concentration of a solution. Molarity, mole fraction, normality, molality are some examples. Here 7 mol / L is also called 7 M.
What is molarity?The molarity of a solution is defined as the number of moles of the solute present per litre of the solution. The molarity of a solution is generally expressed in mol / L which is its SI unit. It can also be represented as M.
The equation that is used to calculate the molarity is:
Molarity = Number of moles of the solute / Volume of the solution in litres
If the mass of the solute (w₂) of molecular mass (M₂) present in VL (or dm³) of the solution, then the molarity is given by:
M = w₂ / M₂ × V
Here the solution 7 mol per L can also be designated as 7 M.

What is the effect of adding more water to the following equilibrium reaction?
CO2 + H2O —> 2H2CO3
Answer:
The reaction will be driven forward (to the right), creating more 2H2CO3
Explanation:
Reactions maintain balance so if you add more to the left side of the equation, the right side of the equation will increase
