Answer:

  (c)  6.00 M

Step-by-step explanation:

The given equation can be solved for the unknown concentration.

__

  [tex]m_iv_i=m_fv_f\\\\m_i(35.0\text{ ml})=(1.40\text{ M})(150.0\text{ ml})\\\\m_i=\dfrac{(1.40\text{ M})(150.0\text{ ml})}{35.0\text{ ml}}\\\\\boxed{m_i=6.00\text{ M}}[/tex]

The concentration of the stock solution is 6 M.

Answer: c- 6.00 m
