Question

how to calculate Empirical formula and Empirical mass​

Answer 1

Answer:

Determine the empirical formula mass by multiplying each element's subscript by its atomic weight on the periodic table and adding them together

Answer 2

Answer:

By definition, the empirical formula is the SIMPLEST whole number ratio that defines constituent atoms in a species. The ratio of atoms in that species is 1:2:1 with respect to carbon, hydrogen, and oxygen.

The molecular formula is ALWAYS a mulitple of the empirical formula. Here (EN)n = MF = (CH 2 O) ×3 = C 3 H 6 O 6 as required...

Determine the empirical formula mass by multiplying each element's subscript by its atomic weight on the periodic table and adding them together.

Empirical formula for mass =

$(1 \times 12.0107) + (2 \times 1.00794) + (1 \times 15.999)$

$= 30.026$
