The empirical formula is CH2O since there are no common factors (other than 1) in the subscripts. CH2O is the molecular formula because the subscripts give the actual number of atoms of each element in the molecule.

Answer 2

Since both submerged blocks are the same size, they displace the same volume of water.

So the mass is 52.94%
