Molarity is defined as the moles of solute per liter of solution.
. Where M is molarity, n is the number of moles and V is the volume. First we must find the molar mass of
which is 109.98 g/mol


Then we find the molarity using above equation

Well the answer to number 1 is definitely B
number 2 is B
number 3 is D
Number 4 is C
Hope this helps:)
