What is the molarity of a solution containing 3.5 moles of hcl in 5.0 l of water?

a) 0.70 m
b) 1.4 m
c) 3.5 m
d) 18 m.

0.70 M

Explanation:

In this case;

We are given;

Number of moles of HCl = 3.5 Moles

Volume of solvent, H₂O is 5.0 L

But,

Therefore;

                   = 0.70 M

Thus, the molarity of the solution is 0.70 M or 0.70 moles/liter

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
