Represent the gravity of granite is 2.7
The answer for your question is 0.27g/L
False, Atoms are the smallest units of matter that display both the chemical and physical properties of it, based on the structure of the atom.
Answer
The empirical formula is CrO₂Cl₂
Explanation:
Empirical formula is the simplest whole number ratio of an atom present in a compound.
The compound contain, Chromium=33.6%
Chlorine=45.8%
Oxygen=20.6%
And the molar mass of Chromium(Cr)=51.996 g mol.
Chlorine containing molar mass (Cl)= 35.45 g mol.
Oxygen containing molar mass (O)=15.999 g mol.
Step-1
Then,we will get,
Cr= mol
Cl= mol.
O= mol.
Step-2
Divide the mole value with the smallest number of mole, we will get,
Cr=
Cl=
O=
Then, the empirical formula of the compound is CrO₂Cl₂ (Chromyl chloride)
They become more stable because they achieve a full outer shell of valence electrons with the magic number of 8.
