What is the molarity of 4.0 moles of sodium chloride (NaCl) in 125 mL of solution? Hint: 1 L of solution = 1000 mL of solution

Question 19 options:

500 M

32 M

0.50 M

0.032 M

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.
