For which compound is the empirical formula the same as the molecular formula?

Thus empirical and molecular formula is sa,e for

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.  

1. The empirical formula is

The empirical weight of = 1(12)+2(16)+1(1)= 45g.

The molecular weight = 90 g/mole

Now we have to calculate the molecular formula:

The molecular formula will be=

2. The empirical formula is

The empirical weight of = 1(12)+3(1)+1(16)= 31 g.

The molecular weight = 62 g/mole

Now we have to calculate the molecular formula:

The molecular formula will be=

3. The empirical formula is

The empirical weight of = 2(12)+4(1)+1(16)= 44 g.

The molecular weight = 88 g/mole

Now we have to calculate the molecular formula:

The molecular formula will be=

4. The empirical formula is

The empirical weight of = 4(12)+8(1)+1(16)= 72 g.

The molecular weight = 72 g/mole

Now we have to calculate the molecular formula:

The molecular formula will be=

they emit helium gas that attaches to nearby planets.

they remove low-mass elements from the planets’ crust.

they cause nuclear fusion inside the inner core of planets.

they produce heavy elements such as iron and gold.
