What is volume?

Volume is the space occupied by a three-dimensional object.

By the formula [tex]\rm M_1V_1= M_2V_2[/tex]

M1 is the initial molarity, 1.5 M

M2 is the final molarity, 0.800 M

V1 is the initial volume

V2 is the final volume, 2.00 L

Putting the values in the equation

[tex]\rm 1.5\;M \times V_1= 0.800\;M \times 2.00\;L\\\\V_1 = \dfrac{ 0.800\;M \times 2.00\;L}{1.5\;M} = 1066.7\;ml[/tex]

Thus, the initial volume is 1066.7 ml
