4
What is the formula for a compound containing aluminum atoms and also three times as many chlorine atoms as there are aluminum atoms?
The formula would be AlCl3, which is aluminum chloride.
Does no and no2 have the same empirical formulas?
No: The formula NO shows equal numbers of nitrogen and oxygen atoms in the compound, but the formula NO2 shows twice as many oxygen atoms as nitrogen atoms.
How many oxygen atoms are in a formula unit of sodium acetate?
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
How many atoms are represented in the formula?
A chemical formula is the representation of a molecule of a chemical compound; all the atoms from the molecule of this compound need to be represented in the formula.

yes it does
What compound Ba(NO3)2 includes how many atoms?
Barium nitrate has 9 atoms in the formula unit.
What is importance of naming chemical formula?
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of the atoms of the elements present in the compound as well as how many there are for each element in the form of subscripts
