Empirical formula of the compound

Solution:

The empirical formula of a compound is it's simplest ratio by which the elements in the compound combines. It differs from the molecular formula that shows the actual atomic ratios.

To find the empirical formula, follow this process;

Elements                     K                               O

Mass                          36.7                            7.51

Molar

mass                            39                            16

Number of

moles                       36.7/39                    7.51/16

                                   0.94                        0.47

Divide by

the smallest              0.94/0.47               0.47/0.47

                                         2                              1

  Empirical formula is        K₂O

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
