Acertain compound is made up of one phosphorus (p) atom, three fluorine (f) atoms, and one oxygen (o) atom. what is the chemical formula of this compound? note: you will need the periodic table for this question. express your answer as a chemical formula.

The chemical formula for the given compound is

Explanation:

We are given:

A chemical compound has 1 phosphorus atom (P), 3 fluorine atoms (F) and 1 oxygen atom (O).

The chemical formula will contain as many number of atoms, as the given ones.

Thus, the chemical formula for the given chemical compound is

This compound is named as phosphoryl fluoride.

answer; protein;

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
