Answer:

1190\ \text{mL}

Explanation:

M_1 = Initial Concentration of KCl = 2.7 M

V_1 = Volume of KCl = 1 M

M_2 = Final concentration of KCl = 1 M

V_2 = Amount of water

We have the relation

M_1V_1=M_2V_2\\\Rightarrow V_2=\dfrac{M_1V_1}{M_2}\\\Rightarrow V_2=\dfrac{2.7\times 700}{1}\\\Rightarrow V_2=1890\ \text{mL}

The amount of water that is to be added is 1890-700=1190\ \text{mL}.
