A) 0.045 mol/L
B) 2.3 M
C) 9.2 mol/L
D) 17 L

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

i believe the answer is true.
