Molarity = mol/L

0.175 mol
0.15 L (1000 mL = 1 L)

Molarity = 0.175 mol/0.15 L = 1.1666667 M

Step-by-step explanation:

Molarity is the number of moles present in liter of a solution.

Mathematically, Molarity =
\frac{\text{no. of moles}}{\text{volume in liter}}

It is given that no. of moles present into the solution are 0.175 mol and volume is 150 ml.

As 1 ml = 0.001 L. So, 150 ml will be equal to 0.15 L.

Hence, calculate the molarity as follows.

Molarity =
\frac{\text{no. of moles}}{\text{volume in liter}}

=
(0.175 mol)/(0.15 L)

= 1.16 M

Thus, we can conclude that molarity of the given solution is 1.16 M.
