first change cm to m and g to kg so you will find the volume first which is 0.02 by 0.03 by 0.02 your answer is 0.000012 m . using the formula density=mass/volume take 0.094/ 0.00012 then divide
We should apply the law of conversation of mass to balance any chemical reaction; that the no. of atoms in the reactants side is equal to that in the products side.
