Ex 2:Give the empirical formula for:a) glucose: C6 H12 O6b) sucrose: C12 H24 O12c) C6 H6d) C4 H5 O3What are the possible molecular formula for the empirical formula:C2 H3 O

a) The empirical formula for glucose (C6 H12 O6) is CH2O. This is found by dividing the number of each atom by the greatest common factor. In this case, the greatest common factor is 6.

b) The empirical formula for sucrose (C12 H24 O12) is also CH2O. Again, this is found by dividing the number of each atom by the greatest common factor, which is 12 in this case.

c) The empirical formula for C6 H6 is CH. The greatest common factor is 6, so we divide each atom by 6.

d) The empirical formula for C4 H5 O3 is C4H5O3. The greatest common factor is 1, so the empirical formula is the same as the molecular formula.

For the empirical formula C2 H3 O, the possible molecular formulas could be multiples of the empirical formula. For example, C4 H6 O2, C6 H9 O3, C8 H12 O4, etc. These are found by multiplying each atom in the empirical formula by the same factor.
