In every 100g of that compund there is 50.84 g of C, 8.53 g H and (100-59.37) g = 40.63 g of O.
Step 1: Convert each element's mass in moles. To do that we need to divide each element's mass by their respective molar mass.
For Carbon.
For Hydrogen.
For Oxygen.
Step 2: Divide each of the numbers by the smallest number.
For Carbon.
For Hydrogen.
For Oxygen.
Step 3: So the empirical formula will be.
But using decimal will be messy. So we multiply the numbers by 3. The right empirical formula will be.
Answer:-
Explanations:- It is given that the charge for A is +2 and the charge for B is -3. The over all compound is neutral means the over all charge is zero. For making the over all charge zero, we need 3 positive ions and 2 negative ions. This makes a +6 charge for A and -6 charge for B and the over all charge is zero.
Also, if we think about the criss cross then charge of A becomes the subscript of B and the charge of B becomes the subscript of A.
So, the formula of the ionic compound is . In this compound the ratio of A to B is 3:2.
The balanced equation could be shown as:
