The statement that best represents the law of conservation of matter with regard to chemical reactions would be the one that says the <u>reactants and products have the same number and type of atoms, but the atoms may be recombined.</u>
First, it is important to know that chemical reactions involve the breaking of bonds between atoms in reactants and the recombination of the atoms in products.
The law of conservation of matter also states that matter (atom) can neither be created nor destroyed in a reaction, but can be converted from one form to another.
Thus, going by the above points, the number of atoms of each element in reactants must also be the same in products. However, recombination of the atoms would most likely have occurred before reactions can take place.

Moles= number of molecules/Avogadro’s constant
(3.8 x 10^24) /(6.02 x 10^23)
=6.31229..
Volume=moles*24(molar gas volume under STP)
= 6.31229...*24
= 151.5 dm^3 (units mainly used in the UK)
=. 151.5 litres
