Answer 1

Вот, в файле все есть. Вроде верно

Answer 2

To find the empirical formula of a compound, we need to know the percentage composition of its elements or the masses of its constituent elements. Unfortunately, the chemical formula "Cr(NO3)3" you provided does not give us enough information to determine the empirical formula.

The chemical formula "Cr(NO3)3" tells us that the compound contains chromium (Cr) and nitrate ions (NO3-). However, it doesn't specify the relative proportions of these elements, which are essential for calculating the empirical formula.

If you have additional information about the mass or percentage composition of each element in the compound, please provide that, and I will be happy to assist you in finding the empirical formula.
