Answer:
Option D
Explanation:
Molarity (M) of any solution is equal to the number of moles (n)of solute in it divided by total volume of solution (V)
Mathematically, it can be represented as
Substituting the given values, we get-
Hence, option D is correct
The "Ideal Gas Law Equations" is
P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>n</u>umber (in moles)
R= 8.3145
or 
T= Temperature (In Kelvin)
Plug into the equation and you're good!
If your teacher cares about sig figs,
2 sig figs (significant figures)
For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />
