to separate objects or ideas into group based on ways they are alike
The law of conservation of mass applies to every reaction. In this case, you start with 1 Mg, 2 H, and 2CL and end up with the same five only their bonds have been rearranged, or in other words, they are joined up differently.
Answer:

Explanation:
Hello!
In this case, as we know the mass of the total sample, we can first compute the mass of oxygen:

Next, we compute the moles of each element:

Now, we divide the moles by 0.184 moles, the fewest ones, to obtain:

Therefore, the empirical formula is:

Molar mass = 133.34 g/mol
